What Fashion Jewellery Is Made Of: Materials, Durability, Care and Allergies

What Fashion Jewellery Is: The Definition in Plain English

Fashion jewellery is jewellery made from non-precious materials. It is also called costume jewellery. The pieces look like fine jewellery, but the metals and stones inside them are cheaper and less durable. That is the trade. You get the look for a fraction of the price, and you accept that the piece will not last as long as solid gold or platinum.

Fashion jewellery is not one material. It is a family of materials. A single necklace can contain a brass chain, a gold coloured coating, glass stones, and resin beads. Each part wears differently. That is why one piece can look perfect after a year while another goes patchy after a month. The difference is what it is made of.

This guide covers each material in turn. You will learn what sits under the surface, how long each material lasts, which ones cause allergies, and how to care for each one.

The Base Metals Under the Plating: Brass, Copper and Zinc Alloy

Most fashion jewellery starts with a base metal. The base metal gives the piece its shape and weight. The shiny surface you see is usually a thin coating over that base. The three common base metals are brass, copper, and zinc alloy.

Brass is the most common base metal in fashion jewellery. It is an alloy of copper and zinc. It is cheap, easy to shape, and takes plating well. Brass can darken with air and skin contact, which is why plated brass pieces can develop dark patches when the coating wears thin.

Copper is soft and warm in colour. It is used for wire work and for pieces where the maker wants a reddish tone. Pure copper tarnishes quickly and can leave green marks on skin. That is why copper is usually plated or lacquered rather than left bare.

Zinc alloy is the cheapest base metal. It is light, it casts easily into detailed shapes, and it is used for chunky pendants, brooches, and statement pieces. Zinc alloy can be brittle. Thin parts can snap if the piece is dropped or bent. It also corrodes faster than brass if the coating fails.

The base metal matters most when the coating wears off. A piece with a brass base will age better than one with a zinc alloy base, because brass is more stable. When you buy fashion jewellery, ask what the base metal is. If the listing does not say, assume it is zinc alloy and treat the piece gently.

Plated Fashion Jewellery: Gold Plated, Silver Plated and Rhodium Plated

Plating is a thin layer of metal deposited onto the base metal. It is what gives fashion jewellery its colour and shine. The three common platings are gold plated, silver plated, and rhodium plated.

Gold plated jewellery has a thin layer of gold over a base metal. The gold layer is measured in microns. Fashion pieces often have less than 0.5 microns. That is very thin. It will wear through with daily use, especially on rings and bracelets that rub against skin and surfaces. Gold plated pieces are not the same as vermeil, which uses a sterling silver base and a thicker gold layer. Our guide to gold plated jewellery explains how plating thickness works and why it matters.

Silver plated jewellery has a thin layer of silver over a base metal. It looks like sterling silver at first, but it tarnishes faster and the plating wears through sooner. Once the base metal shows, the piece cannot be polished back to new. Silver plated jewellery suits occasional wear, not everyday wear.

Rhodium plated jewellery has a layer of rhodium, a hard white metal from the platinum family. Rhodium plating is used to give silver coloured pieces a bright, tarnish resistant finish. It is also used over gold plated pieces to protect the gold layer. Rhodium plating is tougher than gold or silver plating, but it still wears through on rings and bracelets over time.

All plating wears. The question is how fast. Perfume, sweat, water, and friction all speed up plating loss. Pieces that sit still, like pendants, keep their plating longer than pieces that rub, like rings. When plating fails, the base metal shows through as a patchy or dark area. That damage cannot be polished away.

Resin Jewellery: Epoxy Resin, UV Resin, Durability and Yellowing

Resin jewellery is made from a liquid plastic that hardens into a clear or coloured solid. It is used for statement earrings, chunky rings, and pendants with flowers or glitter set inside. There are two common types: epoxy resin and UV resin.

Epoxy resin is mixed from two parts and hardens over hours. It is the stronger of the two. It gives a hard, glass like finish. UV resin hardens in minutes under ultraviolet light. It is quicker to make, but it is often softer and more prone to yellowing.

So, is resin jewellery durable? The honest answer is that it depends on the resin and the wear. Good epoxy resin pieces can last years if they are kept away from heat, sunlight, and chemicals. Cheap UV resin pieces can yellow within months. Yellowing is the main weakness of resin. Sunlight is the biggest cause. A resin piece left on a sunny windowsill will turn yellow faster than one kept in a box.

Resin also scratches more easily than metal or glass. It can crack if it is dropped on a hard floor. Alcohol, including perfume, can cloud the surface. For care, keep resin jewellery away from perfume, hairspray, and strong cleaners. Wipe it with a dry soft cloth only. Do not leave it in direct sunlight or near radiators. Stored well, resin jewellery is a fun and affordable part of a collection. It is not a piece to wear every day in all conditions.

Glass, Crystal and Beads: What They Are and How They Wear

Glass is one of the oldest jewellery materials. Glass beads, glass stones, and glass pendants are common in fashion jewellery. Good glass is hard, it keeps its colour, and it does not tarnish. It can chip or crack if it is dropped, but it does not fade or wear out in normal use.

Crystal is glass with added lead or a similar compound that makes it sparkle more. Crystal stones, often sold under brand names, are cut to catch light like a diamond. They are popular in earrings and pendants. Crystal keeps its shine well, but the foil backing on some crystal stones can peel if the piece gets wet. Keep crystal jewellery dry and wipe it with a soft cloth.

Beads come in many materials: glass, wood, ceramic, and acrylic. Glass beads are the most durable. Wooden beads are light and warm, but they absorb water and perfume, so they need to stay dry. Ceramic beads are hard and colourfast, but they can chip if knocked. When you buy beaded jewellery, check what the beads are made of, because that decides how you should care for the piece.

Acrylic and Plastic Jewellery: Light, Cheap and Short-Lived

Acrylic and plastic jewellery is the lightest and cheapest category. It is used for bold statement earrings, chunky bangles, and colourful beads. Acrylic can be moulded into almost any shape and colour, which is why designers love it for experimental pieces.

The downside is durability. Acrylic scratches easily. It can crack under pressure. Heat can warp it. A pair of acrylic earrings left on a car dashboard in summer can lose its shape. Perfume and nail polish remover can cloud or melt the surface.

Acrylic jewellery is best treated as seasonal and fun rather than long term. Wear it for occasions, keep it away from heat and chemicals, and store it so pieces do not scratch each other. At its price, replacing a piece is often cheaper than trying to repair it.

Synthetic Stones: Cubic Zirconia, Glass Stones and Rhinestones

Fashion jewellery rarely uses real gemstones. Instead it uses synthetic stones that look similar for a fraction of the price. The three common ones are cubic zirconia, glass stones, and rhinestones.

Cubic zirconia is a lab made stone that looks like a diamond. It is hard, clear, and sparkly. It is the closest diamond lookalike in fashion jewellery. Cubic zirconia can cloud over time if it is exposed to lotion, soap, and perfume, but gentle cleaning restores its shine. It is a good choice for earrings and pendants that you want to look expensive without the cost.

Glass stones are simply shaped glass. They are cheaper than cubic zirconia and less sparkly, but they come in every colour. They are used in costume pieces where colour matters more than sparkle. Glass stones keep their colour well, but the foil backing on some can peel if the piece gets wet.

Rhinestones are small glass or acrylic stones with a foil back. They are glued onto metal, fabric, or plastic. Rhinestones are the least durable of the three. The glue loosens with heat, water, and age, so stones fall out. If you buy rhinestone jewellery, check that the stones are set tightly, and keep the piece dry.

None of these stones are diamonds, and honest sellers do not claim they are. When a listing says “diamond” without a qualifier, be sceptical. Real diamonds come with certification and a price to match.

How Long Each Material Lasts: A Durability Comparison

Durability depends on how often you wear a piece and how you care for it, but a rough comparison helps you set expectations.

Material	Typical life with regular wear	Main weakness
Brass base with gold plating	6 months to 2 years	Plating wears through, then base darkens.
Silver plated	6 months to 1 year	Tarnish and plating loss.
Rhodium plated	1 to 3 years	Plating wears on rings and bracelets.
Stainless steel	Many years	Very resistant, rarely tarnishes.
Resin (epoxy)	2 to 5 years	Yellowing and scratches.
Resin (UV)	Months to 2 years	Yellowing, softer surface.
Glass and crystal	Many years	Chipping if dropped, foil backing can peel.
Acrylic and plastic	Months to 1 year	Scratches, heat warping, chemical clouding.
Cubic zirconia	Many years	Clouding from product build up, cleaned easily.
Rhinestones	Months to 1 year	Stones fall out as glue fails.

The pattern is clear. Metals with thin plating have the shortest life. Hard materials like glass, crystal, and cubic zirconia last longest. Resin and acrylic sit in the middle, with sunlight and chemicals as their main enemies.

Which Materials Cause Allergies: Nickel, Copper and Safe Choices

Allergies are one of the most common problems with fashion jewellery. The main cause is nickel. Nickel is used in many cheap alloys to add strength and shine. It is also the most common metal allergen. A nickel allergy causes itching, redness, and a rash where the jewellery touches skin. Ears are the most sensitive area.

Copper can also cause problems. Copper can leave green marks on skin. That green mark is not always an allergy, it is a reaction between copper, sweat, and air, but it can look alarming. People with sensitive skin often react to copper too.

Safe choices for sensitive skin include stainless steel, titanium, sterling silver, and pieces clearly labelled nickel free. Stainless steel is the most affordable safe option. Titanium is even better, but it is harder to find in fashion jewellery and costs more. Sterling silver is a good choice for earrings, because it is widely available and rarely contains nickel.

Be careful with labels. “Hypoallergenic” has no legal definition in jewellery. A piece can be labelled hypoallergenic and still contain nickel. “Nickel free” is a stronger claim, but it still pays to buy from a seller who states the exact metal. If you react to a piece, stop wearing it. A rash that keeps coming back is a sign to switch materials, not to push through.

How to Care for Each Material: Cleaning, Storage and Wear Rules

Care rules differ by material, but three habits protect almost every piece. First, put jewellery on last, after perfume, lotion, and hairspray. Second, take it off before showering, swimming, and exercise. Third, store each piece separately so pieces do not scratch or tangle.

For plated jewellery, use a dry soft cloth only. Water, soap, and jewellery cleaners can speed up plating loss. Wipe the piece after each wear and store it in a dry pouch. For cleaning solid gold, see our guide on how to clean gold jewellery at home.

For pearls and soft stones, use a dry soft cloth only. Never use soap, vinegar, or ultrasonic cleaners on pearls. For gentle methods, see our guide on how to clean pearl jewellery at home.

For resin and acrylic, keep pieces away from perfume, sunlight, and heat. Wipe with a dry cloth. Do not use alcohol based cleaners. For glass, crystal, and cubic zirconia, a soft cloth barely dampened with plain water is safe, followed by full drying. For rhinestones, keep the piece dry, because water loosens the glue.

For stainless steel and titanium, care is simple. Warm water and a soft cloth are enough. These metals tolerate more than plated pieces, but perfume and lotion still leave a film, so a quick wipe after wear keeps them bright.

Fashion Jewellery vs Fine Jewellery: Price, Durability and When Each Wins

Fashion jewellery and fine jewellery serve different purposes. Fashion jewellery wins on price, variety, and trend. You can try a new style for a few pounds, wear it for a season, and move on. Fine jewellery wins on durability, resale value, and long term wear. A solid gold ring can be worn daily for decades. A plated ring cannot.

The smart approach is to split your collection. Buy fashion jewellery for trends, statement pieces, and colours you may not want next year. Buy fine jewellery for pieces you will wear every day, like a wedding band, a signet ring, or a pair of studs. That split gives you variety without wasting money on plated versions of pieces that need to last.

Price is the clearest guide. If a piece costs under 50 pounds and claims to be gold, it is plated or gold toned, not solid gold. That is fine, as long as you know what you are buying. The problem comes when a seller hides the material. Always check the listing for base metal, plating thickness, and stone type before you buy.

Frequently Asked Questions About Fashion Jewellery Materials

What is fashion jewellery made of?

Fashion jewellery is made from base metals like brass, copper, and zinc alloy, often with a thin plating of gold, silver, or rhodium. Stones are usually glass, crystal, cubic zirconia, or rhinestones. Resin, acrylic, and beads are also common. No single material defines fashion jewellery. It is a mix.

Is resin jewellery durable?

Good epoxy resin is fairly durable and can last years with care. UV resin is softer and yellows faster. Both types suffer from sunlight, heat, and perfume. Keep resin jewellery in a box away from windows, and wipe it with a dry cloth only.

Is fashion jewellery hypoallergenic?

Not always. Much fashion jewellery contains nickel, which is the most common metal allergen. If you have sensitive skin, look for pieces labelled nickel free and made from stainless steel, titanium, or sterling silver. “Hypoallergenic” alone is not a guarantee.

Does fashion jewellery tarnish?

Yes. Plated pieces tarnish when the coating wears and the base metal is exposed. Silver plated pieces tarnish fastest. Storing pieces dry, keeping them away from perfume, and wiping them after wear slows tarnish down, but it does not stop it forever.

Can fashion jewellery be repaired?

Sometimes. A jeweller can re-plate a plated piece, but re-plating often costs more than the piece is worth. Broken chains and clasps on cheap pieces are usually cheaper to replace than to repair. Glass and resin pieces are hard to repair once cracked.

What is the difference between fashion jewellery and costume jewellery?

There is no real difference. The two terms mean the same thing: jewellery made from non-precious materials. Fashion jewellery is the more common term in the UK today. Costume jewellery is the older term.

Conclusion

Fashion jewellery is not one material, it is a mix of base metals, platings, resins, glass, and synthetic stones. Each material has its own life span, its own weakness, and its own care rules. Plated pieces need the gentlest care. Glass, crystal, and cubic zirconia last longest. Resin and acrylic need protection from sunlight and chemicals. If you have sensitive skin, check the metal before you buy, and treat “hypoallergenic” as a claim to verify, not a promise.
