CATEGORY 1

Earring Styles and Types

Architectural earring

An earring with strong geometric or sculptural form, characterised by clean lines, defined edges, and intentional design language. Architectural earrings are distinct from traditional ornate or floral designs, reflecting modern minimalist and contemporary aesthetic movements. Often produced in solid gold, surgical steel, or platinum.

Chandelier earring

A large, multi-tiered drop earring designed to resemble the layered structure of a chandelier. Chandelier earrings typically feature cascading chains, gemstones, or metalwork and hang 5 to 10cm below the lobe. They are occasion earrings, associated with formal and evening wear.

Climber earring

An earring (also called a crawler earring) inserted through a standard lobe piercing that is designed to travel upward along the curve of the ear rather than hanging downward. A single piece creates the visual impression of multiple piercings ascending the helix.

Clip-on earring

An earring designed to attach to the earlobe without a piercing, using a mechanical clasp. Modern clip-on mechanisms include omega backs, screw backs, and paddle backs. See Backs and Fastenings for detail on each type.

Cluster earring

An earring composed of multiple small stones or pearls grouped tightly together to form a single visual element. Cluster designs create the appearance of a larger statement piece while using smaller components. Common in pearl, diamond, and gemstone earrings, particularly in floral arrangements where the cluster mimics petals.

Crawler earring

Alternative term for climber earring (see above). The terms are interchangeable, with climber more common in European jewellery markets and crawler more common in North American terminology.

Cuff earring

An earring (also called an ear cuff) that grips the outer cartilage ridge of the ear, specifically the helix, by tension, requiring no piercing. Ear cuffs range from minimal single-band styles to sculptural pieces covering a significant portion of the outer ear. The terms ear cuff and cuff earring are interchangeable.

Dangle earring

A drop earring with a longer, freely moving element that sways with movement. Distinguished from a standard drop earring by its length and mobility. A dangle typically extends more than 3cm below the lobe and moves visibly when the wearer moves.

Drop earring

Any earring with an element that hangs below the lobe, typically in a relatively still, short drop of 1 to 3cm. Drop earrings are distinguished from dangle earrings by their shorter length and more restrained movement. For complete drop earring coverage, see the dedicated guide.

Ear cuff

See cuff earring (above). The terms are interchangeable.

Ear jacket

A two-part earring consisting of a front stud and a separate decorative element that attaches behind the earlobe. From the front, only the stud is visible. The jacket piece frames the lobe from behind, visible at an angle. Ear jackets are worn in a standard lobe piercing.

Floral drop earring

A drop earring featuring flower or petal motifs, typically in pearl, gemstone, or sculpted metal. Floral drops fall within the romantic aesthetic register and work particularly well for square and angular face shapes that benefit from soft curved design contrast.

Geometric earring

Any earring built around defined geometric shapes (triangles, squares, hexagons, circles, rectangles) rather than organic or floral forms. Geometric earrings are central to the modern architectural aesthetic and work harmoniously with contemporary fashion.

Hoop earring

A circular or near-circular earring that passes through the ear and closes on itself. Hoops range from 10mm (very small, close to the lobe) to 80mm or larger. Huggies are a subcategory of hoop. The hoop is one of the oldest earring forms in recorded history, with examples found in ancient Mesopotamia dating to approximately 2500 BCE.

Huggie earring

A small hoop earring specifically designed to sit tightly against the earlobe. Huggies are typically 8 to 14mm in diameter and are distinguished from standard hoops by their close fit rather than their circular shape. The term derives from the earring hugging the lobe.

Jacket earring (see: ear jacket)

Mismatched earrings

A deliberate styling choice in which the two earrings worn are intentionally different, with different shapes, sizes, or designs that are clearly not a pair. Mismatched earrings became a significant trend in fine and fashion jewellery from approximately 2015 onwards and remain a recognised styling approach in 2026.

Statement earring

Not a specific style but a category defined by intent and scale. Any earring type (hoop, drop, chandelier, cuff) that is large, bold, or unusual enough to anchor and define a look is considered a statement earring. The defining characteristic is that the earring is the primary focal point of the overall look. For complete statement earring coverage, see the dedicated guide.

Stud earring

The most widely worn earring style globally. A stud sits directly on the earlobe with no hanging element, held in place by a backing. The visible face of a stud is typically a gemstone, metal shape, or pearl. Studs range from 3mm (minimal) to 10mm (bold) in diameter. For complete stud coverage, see the dedicated guide.

Tassel earring

A drop earring featuring multiple chains or strands hanging from a central focal element to create a tassel-like cascade. Tassel earrings are typically long (4cm or more) and create visible movement when worn. They emphasise length and verticality.

Threader earring

An earring consisting of a thin chain or wire that passes directly through the piercing hole, with length hanging on both sides of the ear. There is no post, no backing, and no mechanism. The earring rests in the piercing by gravity. Threaders produce an extremely delicate, minimal aesthetic.

CATEGORY 2

Earring Backs and Fastenings

Barrel back

A cylindrical screw-on earring back (also called torpedo back or bullet back) that provides a secure hold. Common on heavier earrings where a standard butterfly back might not hold reliably. The barrel screws onto the post rather than pushing on.

Butterfly back

The most common earring fastening (also called friction back or push back). A small metal finding with two curved wings that grip the post by friction when pushed on. Butterfly backs are secure for everyday wear but can loosen over time with repeated use.

Clutch back (see: butterfly back)

Flat disc back

A backing (also called labret back or flat back) with a flat, circular disc rather than a butterfly or barrel shape. The disc sits flush against the back of the earlobe, making it significantly more comfortable for sleeping and for earrings worn in cartilage piercings. Flat disc backs are the recommended backing for newly pierced ears as they minimise pressure and movement.

Friction back (see: butterfly back)

Hinge closure

The fastening mechanism used on most hoop earrings. A small hinge on the hoop opens to allow insertion and snaps shut to close, holding the earring in place. The click of a hinge closure indicates it is fully secured.

Latch back

A hinged closure (also called leverback) used on drop and dangle earrings. A hook passes through the piercing and a hinged latch swings up behind it to close, creating a more secure hold than a standard open hook. Leverbacks are preferred for heavier earrings and active lifestyles.

Leverback (see: latch back)

Omega back

A clip-on mechanism in which a hinged clasp shaped like the Greek letter Ω closes over the earlobe. The omega back distributes pressure evenly across the lobe, making it the most comfortable clip-on mechanism for extended wear. Also used on some pierced earrings as an alternative to butterfly backs.

Paddle back

A clip-on fastening with a flat paddle that clips over the lobe. Simpler than an omega back and less adjustable, but easy to operate. Common on lightweight fashion clip-on earrings.

Post

The thin metal rod that passes through the piercing hole. Posts are typically made of the same metal as the earring face, though the post material is particularly important for anyone with sensitive ears. The post has direct contact with the piercing channel and is most likely to cause reactions if made from base metals.

Screw back

An earring back that screws onto the post rather than pushing on, providing a very secure hold that does not loosen with wear. Recommended for valuable earrings (diamonds, precious stones) and for children's earrings where security is important. Slightly more time-consuming to put on and remove than a butterfly back.

Shepherd's hook

An open, curved wire (also called fish hook or French hook) that passes through the piercing and hangs by gravity without a closing mechanism. The most common fastening on drop and dangle earrings. Lightweight and easy to use, but less secure than a leverback. Not recommended for valuable earrings or active wear.

CATEGORY 3

Materials and Metals

Alloy

A mixture of two or more metals. Most jewellery metals are alloys. Pure gold, silver, and platinum are too soft for practical use and are mixed with other metals to add durability. The composition of the alloy determines the metal's colour, hardness, and hypoallergenic properties.

Base metal

Any non-precious metal used as the primary material in a piece of jewellery. Common base metals include brass, copper, zinc, and nickel. Base metals are typically plated with a precious metal finish. The quality of base metal jewellery depends heavily on the thickness and quality of the plating, and on the choice of base metal itself.

Brass

A yellow alloy of copper and zinc. Widely used as a base metal in fashion jewellery. Brass is dense, affordable, and takes plating well, but it contains copper, which can cause a green tint on skin in some wearers. Quality jewellery typically avoids brass as a post material for sensitive ears.

Gold electroplated

A precious metal coating applied to a base metal through electroplating, typically gold or rhodium. Quality electroplating uses thicker coatings (2 to 3 microns or more for daily-wear jewellery). Lower-quality electroplating uses very thin coatings (under 0.5 microns) that wear away within months of normal use.

Gold-filled

A layered metal construction in which a thick layer of gold (minimum 1/20th of the total metal weight, typically 14K or 18K) is mechanically bonded to a base metal core under heat and pressure. More durable than gold-plated jewellery, as the gold layer is significantly thicker and does not wear away with normal use. Not the same as solid gold.

Gold-plated

A base metal item with a thin layer of gold applied to the surface, typically via electroplating. The gold layer in standard plating ranges from very thin (under 0.5 microns, low quality) to thicker plating (2 to 3 microns, quality jewellery). Quality 18K gold plating on surgical steel base provides genuine luxury at accessible prices.

Gold vermeil

Sterling silver with a thick layer of gold plating (pronounced ver-MAY). At minimum 2.5 microns of gold, significantly thicker than standard gold plating. Vermeil is a regulated term in several countries. In the UK and US, an item cannot legally be called vermeil unless it meets the minimum gold thickness and uses sterling silver as the base. A higher-quality alternative to standard gold-plated jewellery.

Hypoallergenic

A term used to describe materials that are unlikely to cause an allergic reaction. In the context of earrings, hypoallergenic materials include implant-grade titanium, solid 14K or 18K gold, platinum, sterling silver 925, and surgical steel 316L with quality gold plating. The term is not regulated, meaning manufacturers can use it loosely. Always check the specific material rather than relying on the label alone.

Karat (K)

The unit of measurement for the purity of gold, expressed as a fraction of 24 parts. 24K gold is pure gold (100%). 18K gold contains 18 parts gold and 6 parts other metals (75% pure). 14K gold contains 14 parts gold (58.3% pure). 9K gold (37.5% pure) is the minimum legal standard for gold in the UK. Higher karat gold is purer but softer. Lower karat gold is more durable but less pure.

Nickel

A silvery-white metal used in many base metal alloys and in some gold alloys as a whitening agent. Nickel is the most common cause of metal contact allergy, estimated to affect 10 to 15% of women and 1 to 2% of men. The EU restricts nickel content in jewellery in contact with skin to 0.5 micrograms per cm² per week (Nickel Directive 94/27/EC). Anyone with a nickel allergy should avoid nickel-plated jewellery entirely.

Platinum

A naturally white, dense, and extremely durable precious metal. Platinum jewellery is typically 95% pure (950 platinum) and is one of the most hypoallergenic metals available. Heavier than gold, more expensive, and highly resistant to tarnishing. Used for investment and heirloom pieces.

Rhodium

A rare platinum-group metal used as a plating on white gold and silver to increase brightness, hardness, and tarnish resistance. Most white gold jewellery is rhodium-plated, as the rhodium gives it its bright, mirror-like finish. Rhodium plating wears away over time and may need reapplication after several years of regular wear.

Rose gold

A gold alloy with a warm pink tone, achieved by mixing gold with copper. The more copper in the alloy, the deeper the pink. 14K rose gold typically contains approximately 58% gold, 33% copper, and 9% silver. Rose gold does not tarnish but the copper content can occasionally cause reactions in people with copper sensitivities.

Sterling silver (925)

An alloy of 92.5% silver and 7.5% other metals, typically copper. The copper adds the hardness that pure silver lacks. Sterling silver is marked 925. It is an affordable, widely available, and generally skin-safe metal, though it tarnishes with exposure to air and certain chemicals. Rhodium-plated sterling silver tarnishes significantly more slowly than untreated sterling.

Surgical steel (316L)

Medical-grade stainless steel designed for prolonged contact with human tissue. The 316L designation refers to the specific alloy composition used in surgical implants, medical instruments, and quality body piercings. Surgical steel is the preferred base material for quality hypoallergenic earrings, often paired with 18K gold plating to combine medical-grade safety with luxury visual quality. Used as the base for virtually all quality Clarabelle earrings.

Titanium

A lightweight, extremely strong metal considered the gold standard for hypoallergenic jewellery. Implant-grade titanium (ASTM F136) contains no nickel and is used in medical implants precisely because it is biocompatible with human tissue. The most reliably safe earring material for sensitive or newly pierced ears.

White gold

A gold alloy made by mixing gold with white metals such as palladium, silver, or nickel. White gold is typically rhodium-plated to achieve its bright, silver-like appearance. The alloy itself is slightly off-white or yellowish without plating. If white gold contains nickel (which some formulations do), it may cause reactions in nickel-sensitive individuals. Palladium-based white gold is the safer choice for sensitive wearers.

CATEGORY 4

Pearls and Pearl Terminology

Akoya pearl

A cultured saltwater pearl produced primarily in Japan, prized for its bright lustre and near-perfect round shape. Akoya pearls are typically smaller than other saltwater pearls (4 to 9mm) and are the classic white pearl associated with traditional pearl jewellery. They have the highest lustre of all pearl types and command premium prices.

Baroque pearl

A naturally irregularly-shaped pearl with asymmetric or non-round form. Baroque pearls were historically considered less valuable than perfectly round pearls, but modern jewellery design celebrates their organic shapes as distinctive and contemporary. Each baroque pearl is unique.

Cultured pearl

A pearl produced by inserting a small irritant (a bead or piece of mantle tissue) into a mollusc, which then coats it with nacre to form a pearl. The vast majority of pearls in modern jewellery are cultured. Natural pearls (formed without human intervention) are extremely rare and expensive. Cultured does not mean fake. The pearl is real, formed by the same biological process as natural pearls.

Freshwater pearl

A pearl cultured in freshwater mussels, primarily in China. Freshwater pearls are typically less expensive than saltwater pearls and come in a wider range of natural colours (white, cream, pink, peach, lavender) and shapes (round, baroque, button, oval). Modern freshwater pearl quality has improved significantly and high-quality freshwater pearls now rival saltwater pearls visually.

Lustre

The reflective quality of a pearl's surface. Lustre is the most important factor in pearl quality, more important than size, shape, or colour. High-lustre pearls appear almost to glow from within, reflecting light sharply. Low-lustre pearls appear dull or chalky. Lustre depends on the thickness, smoothness, and uniformity of the pearl's nacre layers.

Mabe pearl

A half-pearl cultivated on the inside shell of an oyster rather than within the mollusc's body. Mabe pearls have a flat back, making them suitable for stud earrings and rings where a full pearl shape is not needed. They are typically larger than full pearls (10 to 20mm) and significantly less expensive.

Mother-of-pearl

The iridescent inner shell lining of pearl-producing molluscs, the same material that coats pearls themselves (nacre). Mother-of-pearl is used as an inlay material in jewellery, watches, and decorative objects. It has a soft, opalescent sheen distinct from pearl itself.

Nacre

The smooth, lustrous material that pearl-producing molluscs deposit in layers to form pearls. Nacre is composed of calcium carbonate crystals and proteins. The thickness and quality of nacre determines the pearl's lustre and durability. High-quality pearls have thick nacre layers (over 0.5mm). Lower quality pearls have thinner nacre that can wear away over time.

Pearl revival

The documented contemporary resurgence of pearl jewellery, particularly evident from 2023 onwards. Driven by red carpet adoption, modern minimalist aesthetics aligning with pearl's quiet sophistication, and the cultural shift from trend-driven to investment-piece consumption. Pearl earrings have returned to peak relevance in 2026 across modern jewellery markets.

South Sea pearl

A large saltwater cultured pearl produced in the warm waters between Australia, Indonesia, and the Philippines. South Sea pearls are the largest cultured pearls (9 to 20mm) and are available in white, silver, gold, and cream colours. They command the highest prices in the cultured pearl market.

Tahitian pearl

A naturally dark-coloured saltwater cultured pearl produced in French Polynesia. Tahitian pearls range from dark grey to black, with overtones of green, blue, purple, and bronze. They are larger than Akoya pearls (typically 9 to 15mm) and command premium prices due to their distinctive natural colour.

CATEGORY 5

Gemstones and Settings

Bezel setting

A setting in which the gemstone is surrounded by a continuous rim of metal that holds it in place. The metal rim covers the stone's girdle entirely. Bezel settings are the most secure setting type and the most protective of the stone's edges, making them well-suited for everyday earrings and active wear.

Birthstone

A gemstone associated with a particular month of the year, traditionally given as a personal piece of jewellery. Modern birthstone lists: January garnet, February amethyst, March aquamarine, April diamond, May emerald, June pearl or alexandrite, July ruby, August peridot, September sapphire, October opal or pink tourmaline, November topaz or citrine, December turquoise or tanzanite. Birthstone earrings are popular as personal gifts.

Channel setting

A setting technique in which multiple small stones are set in a continuous row within a channel of metal, with no prongs visible between them. The stones sit flush within the channel walls. Common in band-style hoops and contemporary stud designs.

Claw setting

Alternative term for prong setting (see below). The terms are interchangeable, with prong more common in North American jewellery and claw more common in UK and European jewellery terminology.

Cubic zirconia (CZ)

A synthesised crystalline material that closely resembles diamond in appearance. Cubic zirconia is optically flawless, significantly less expensive than diamond, and has a high refractive index that produces strong brilliance. Not a gemstone in the mineralogical sense, as it does not occur in nature. Often used in fashion and affordable fine jewellery as a diamond alternative. Quality CZ provides 95% of diamond visual quality at 5 to 10% of diamond price.

Halo setting

A setting in which a central stone is surrounded by a circle of smaller accent stones, creating the appearance of a halo around the central piece. Common in pavé-style earrings and modern engagement-adjacent designs. The halo amplifies the visual size and brilliance of the central stone.

Lab-grown gemstone

A gemstone created in a controlled laboratory environment using the same chemical composition and crystal structure as its natural counterpart. Lab-grown diamonds, sapphires, emeralds, and rubies are chemically identical to mined stones. Lab-grown stones are typically significantly less expensive than equivalent mined stones (often 60 to 80% less) and have guaranteed ethical sourcing.

Pavé setting

A setting technique (pronounced pah-VAY) in which multiple small stones are set very closely together across a surface, held by tiny beads or prongs, with minimal metal visible between them. The effect is a surface that appears entirely covered in stones. The word derives from the French for paved. Common in huggie earrings and hoop bands.

Prong setting

A setting in which the stone is held by small metal prongs (typically four or six) that grip the stone at its girdle. Prong settings expose maximum surface area of the stone, allowing maximum light entry and brilliance. The most common setting for solitaire stones. Also called a claw setting.

Solitaire

A piece of jewellery featuring a single central stone without accompanying accent stones. The solitaire is the classic stud earring format, particularly common in diamond, CZ, and pearl. A solitaire stud focuses entirely on the quality and character of the single stone.

CATEGORY 6

Measurements and Sizing

Gauge

The diameter of an earring post or wire, and correspondingly the size of the piercing channel. Gauge is measured on a scale where a higher number indicates a thinner wire. Counterintuitively, a 20 gauge post is thinner than a 16 gauge post. Standard lobe piercings are typically done at 20 or 18 gauge. Stretched piercings use progressively lower gauge numbers (larger diameter).

Millimetre (mm)

The standard unit for measuring earring dimensions. Stud diameter, hoop diameter, and drop length are all typically expressed in millimetres. A 5mm stud is modest and subtle. A 10mm stud is bold. A 20mm hoop sits close to the lobe. A 50mm hoop is large and striking.

Micron

A unit of measurement equal to one thousandth of a millimetre, used to describe the thickness of plating on gold-plated and vermeil jewellery. Standard gold plating ranges from very thin (under 0.5 microns, low quality) to thicker quality plating (2 to 3 microns). Gold vermeil requires a minimum of 2.5 microns. Flash plating (the thinnest form) is less than 0.175 microns and wears away within months.

Scale (earring)

The overall visual size and presence of an earring. Earring scale is determined by the combination of size, weight, design distinctiveness, and contextual proportions. A 30mm geometric matte hoop reads as larger scale than a 50mm classic gold hoop. Scale is more relevant than absolute size for understanding how an earring will read.

CATEGORY 7

Piercing Terminology

Cartilage piercing

Any piercing in the cartilage of the ear, as opposed to the soft tissue of the lobe. Common cartilage piercings include the helix (upper outer rim), the tragus (the small flap in front of the ear canal), the conch (the inner cartilage cup), and the daith (the innermost cartilage fold). Cartilage piercings take significantly longer to heal than lobe piercings, typically three to twelve months.

Conch piercing

A piercing through the large, flat inner cartilage of the ear (the conch of the shell-like ear structure). Inner conch piercings are worn with studs or barbells. Outer conch piercings can wear hoops. The conch heals in 6 to 12 months.

Curated ear

A styling approach in which multiple earrings across different piercing positions are deliberately coordinated to create a single composed jewellery composition. The curated ear treats the ear as a styling canvas rather than placing earrings randomly. Has become the defining contemporary ear styling approach in 2026, particularly with mixed huggies, studs, and ear cuffs.

Daith piercing

A piercing through the innermost cartilage fold of the ear, just above the ear canal opening. Daith piercings are typically worn with small hoops or curved barbells. They have been claimed anecdotally to help with migraines, though there is no peer-reviewed clinical evidence supporting this association.

Flat piercing

A surface piercing on the flat upper cartilage area of the ear (the scapha or flat plate). Flat piercings are worn with flat-back studs and are popular in curated ear looks as they create a stud at a point where a standard lobe or helix placement would not reach.

Helix piercing

A piercing through the outer rim of cartilage at the top of the ear. The most common cartilage piercing. Helix piercings are worn with small hoops, huggies, or flat-back studs. A forward helix is located at the front curve of the rim, closer to the face.

Lobe piercing

A piercing through the soft tissue of the earlobe. The most common ear piercing type globally. Standard lobe piercings heal in six to eight weeks. A second or third lobe piercing is placed higher on the lobe and heals in a similar timeframe.

Stack (earring)

A styling composition in which multiple earrings of varying sizes are worn across consecutive piercings in the same ear, typically descending in scale from main lobe upward. A typical earring stack might consist of a 6mm stud at the main lobe, a 4mm stud at the second lobe piercing, and a 3mm flat-back stud at the helix.

Tragus piercing

A piercing through the small, thick flap of cartilage that projects from the face in front of the ear canal. Typically worn with a small flat-back stud or a very small hoop. The tragus is dense cartilage and piercings there take three to six months to heal.

CATEGORY 8

Care and Maintenance

Anti-tarnish strip

A small absorbent strip placed inside a jewellery storage box or pouch that absorbs sulphur and moisture from the surrounding air, slowing tarnish formation on silver and silver-plated jewellery. Anti-tarnish strips are most effective for stored jewellery that is not worn regularly. They typically need replacement every 3 to 6 months.

Contact dermatitis

A skin reaction characterised by redness, itching, and sometimes blistering at the site of contact with an irritant or allergen. Jewellery-related contact dermatitis is most commonly caused by nickel. The reaction can develop even after years of wearing a piece without issue, as nickel sensitivity can develop with repeated exposure over time.

Oxidation

A chemical reaction between a metal and oxygen in the atmosphere. Silver oxidises to form silver sulphide, which appears as a dark tarnish on the surface. Some jewellers intentionally oxidise silver to create a dark, antiqued finish, called patinated or oxidised silver. Gold does not oxidise under normal conditions, which is one reason it does not tarnish.

Patina

A surface change in metal caused by oxidation, handling, and age. In silver, patina manifests as tarnish. In copper and brass, it creates the characteristic green coating (verdigris). Some wearers and designers value patina as evidence of age and character. Others prefer to clean it away and restore the original surface.

Plating wear

The gradual erosion of a surface metal coating through friction, chemical exposure, and mechanical wear. Plating wear is most visible at contact points, including earring posts, the inner edge of hoops, and the surface of backs. The rate of wear depends on plating thickness, base metal quality, and how the jewellery is used and stored. Quality 18K plating on surgical steel base typically maintains appearance for 3 to 5+ years of daily wear with proper care.

Polishing cloth

A soft cloth, often impregnated with cleaning compounds, used to remove tarnish and restore shine to jewellery surfaces. Silver polishing cloths are specifically formulated for silver and remove tarnish without abrasion. Gold polishing cloths are gentler and suitable for solid gold and gold-plated pieces. Microfibre cloths work for general cleaning of all jewellery types.

Tarnish

A thin layer of corrosion that forms on the surface of silver, copper, and brass through reaction with sulphur compounds in the air. Tarnish appears as a dull, dark discolouration. It is surface-level and can be removed with a polishing cloth or mild cleaning solution. Regular wear and correct storage slow tarnish formation. Gold does not tarnish. Titanium and platinum do not tarnish.

Ultrasonic cleaner

An electric device that uses high-frequency sound waves to create cavitation bubbles in cleaning fluid, dislodging dirt and tarnish from jewellery surfaces. Ultrasonic cleaners work well for diamonds, gold, and platinum but should not be used on pearls, plated jewellery, or porous gemstones (opals, turquoise, emeralds), as they can damage these materials.

Frequently Asked Questions

What is the difference between gold-plated, gold-filled, and gold vermeil?

All three involve a layer of gold over a base metal, but the thickness varies significantly. Gold-plated has the thinnest layer (typically 0.5 microns or less for standard plating, 2 to 3 microns for quality plating). Gold vermeil requires a minimum of 2.5 microns of gold over sterling silver specifically (regulated term). Gold-filled has the thickest layer (minimum 1/20th of total weight, mechanically bonded). In terms of durability: gold-filled lasts longest, vermeil lasts longer than standard plating, and quality 18K gold plating on surgical steel base is the optimal balance of quality and accessibility.

What's the difference between a stud and a huggie earring?

Studs sit directly on the earlobe with no hanging element, held by a backing. Huggies are small hoop earrings (typically 8 to 14mm) designed to sit tightly against the earlobe, distinguished from standard hoops by their close fit rather than their circular shape. The functional difference: studs are flat against the lobe, huggies wrap around the lobe edge. Both work for continuous daily wear and both flatter virtually every face shape. Huggies offer slightly more visual presence than equivalent-size studs.

What does 18K gold mean?

18K gold contains 18 parts pure gold and 6 parts other metals (typically silver, copper, or palladium), making it 75% pure gold. The remaining 25% adds durability that pure gold lacks. 18K gold has a slightly warmer, more saturated colour than 14K gold (which is 58.3% pure gold), and significantly higher gold content than 9K gold (37.5% pure, UK minimum legal standard). Higher karat gold is purer but softer. Lower karat gold is more durable but contains less actual gold.

What does 925 mean on jewellery?

925 is the hallmark for sterling silver, indicating 92.5% pure silver content. Sterling silver is an alloy of pure silver (which is too soft for jewellery on its own) with 7.5% other metals, typically copper. The hallmark 925 appears stamped on quality sterling silver pieces, often near the clasp or post. Sterling silver is affordable, widely available, and generally hypoallergenic, though it tarnishes naturally over time due to silver's reaction with sulphur in air.

Are surgical steel earrings safe for sensitive ears?

Yes. Surgical steel (specifically 316L grade) is medical-grade stainless steel designed for prolonged contact with human tissue. It is the same material used in surgical implants and medical instruments. Surgical steel is hypoallergenic for virtually all wearers, even those with severe metal sensitivities. Quality earrings combine surgical steel base with 18K gold plating to provide medical-grade safety with luxury visual quality at accessible prices.

What is the difference between cultured and natural pearls?

Cultured pearls are formed when humans intentionally insert a small irritant into a mollusc, which then coats it with nacre to form a pearl. Natural pearls form without human intervention when an irritant accidentally enters a mollusc. The biological pearl-formation process is identical. Cultured does not mean fake or artificial, the pearl is real, formed by the same mollusc using the same nacre. Virtually all pearl jewellery in modern markets uses cultured pearls because natural pearls are extremely rare and prohibitively expensive.

Do I need to take my earrings off to sleep?

Quality flat-back studs and small huggies in hypoallergenic materials are safe for sleeping in continuously. Many women wear them 24/7 without removal. The factors that matter: flat-back design (won't press into ear during sleep), secure closures (won't fall out), and quality materials (won't cause irritation). Avoid sleeping in drops, statement pieces, or earrings with prominent backs that might catch on bedding. For occasional removal at night, store in soft pouches to prevent damage.

What is a curated ear?

A curated ear is a styling approach in which multiple earrings across different piercing positions are deliberately coordinated to create one composed jewellery composition. The curated ear treats the ear as a styling canvas rather than placing earrings randomly. It has become the defining contemporary ear styling approach in 2026. Typical curated ear compositions combine 3 to 5 pieces of varying scales, often in descending size from main lobe upward, in coordinated metals or deliberately contrasting materials.
