The Complete Guide to Enamel Jewellery: Techniques, History & Care

Enamel jewellery is one of the oldest and most captivating forms of decorative art. For thousands of years, artisans have fused powdered glass onto metal to create pieces that glow with colour in a way no gemstone or paint can replicate. At NJewellery, we carry on this ancient tradition using vitreous enamel — real glass fired at high temperatures — to produce handmade rings, earrings, pendants, and bowls that are built to last generations.

This guide covers everything you need to know about enamel jewellery: the major techniques, the history behind them, how to tell quality enamel from cheap imitations, and how to care for your pieces so they stay brilliant for years.

What Is Vitreous Enamel?

Vitreous enamel (also called porcelain enamel or hot enamel) is powdered glass that is fused to a metal surface — typically silver, gold, or copper — by firing in a kiln at temperatures between 750°C and 850°C. At these temperatures the glass particles melt and bond permanently with the metal, creating an incredibly hard, glossy surface that resists scratching, fading, and chemical damage.

This is fundamentally different from cold enamel or resin-based "enamel" found in mass-produced fashion jewellery. Cold enamel is essentially coloured epoxy glued onto metal. It chips easily, yellows over time, and lacks the depth and luminosity of true vitreous enamel. When shopping for enamel jewellery, always check whether the piece uses vitreous (hot) enamel or resin — the difference in durability and beauty is enormous.

Major Enamel Techniques

Cloisonné

Cloisonné is perhaps the most recognised enamel technique. The word comes from the French cloison, meaning "partition." The artisan creates small cells (cloisons) by bending thin strips of wire — usually fine silver or gold — and soldering them onto the metal base. Each cell is then filled with enamel powder and fired in the kiln. The result is a design where fine metal lines separate each colour, giving cloisonné its distinctive stained-glass appearance.

Cloisonné allows for extraordinary detail and colour control. Each cell can hold a different colour or shade, and because the wire outlines are part of the design, they create crisp, precise boundaries. Our Triple Leaf Silver Branch Pendant and Blue Iris Pendant showcase this technique beautifully.

Champlevé

Champlevé (from the French champ levé, meaning "raised field") takes the opposite approach. Instead of building up wire walls, the artisan carves, etches, or engraves recesses into the metal surface, then fills those recesses with enamel powder and fires the piece. The unetched metal remains raised above the enamel, forming the outlines and structure of the design.

Champlevé tends to produce bolder, more sculptural effects than cloisonné. The metal borders are thicker and more prominent, giving the piece a robust, architectural quality. Many of our enamel jewellery pieces use champlevé or a combination of both techniques, like our popular Cherry Blossom Silver Ring and Maple Leaf Earrings.

Combining Techniques

Skilled enamel artists often combine cloisonné and champlevé in a single piece to achieve effects neither technique could produce alone. The carved champlevé recesses provide broad colour fields, while cloisonné wire adds fine detail within or alongside those fields. This hybrid approach is a hallmark of artisan enamel work and something you will rarely find in factory-produced pieces.

A Brief History of Enamel Art

Enamel work dates back at least 3,500 years. The earliest known examples come from ancient Mycenaean Greece and Cyprus, where gold rings and ornaments were decorated with simple enamel inlays. The technique spread throughout the Byzantine Empire, where cloisonné enamel on gold became a supreme art form, producing sacred icons and imperial regalia of breathtaking beauty.

During the medieval period, the city of Limoges in France became the European capital of champlevé enamel, producing religious objects, reliquaries, and decorative plaques. The tradition continued through the Renaissance and into the Art Nouveau period, when artists like René Lalique elevated enamel jewellery to fine-art status with flowing, organic designs.

Today, vitreous enamel remains a living craft practiced by artisans worldwide. At NJewellery, every enamel piece is made by hand in our Australian workshop using the same fundamental techniques that have been refined over millennia — though we bring our own contemporary aesthetic to this ancient art.

How to Judge Enamel Quality

Not all enamel jewellery is created equal. Here are the key things to look for when evaluating a piece:

Surface finish: High-quality vitreous enamel should be smooth, glossy, and free of pits, bubbles, or rough patches. Run your fingernail across the surface — it should feel perfectly even. Uneven surfaces indicate poor firing or low-quality enamel powder.

Colour depth: True vitreous enamel has a luminous, almost liquid depth of colour that catches and plays with light. Compare this to resin or cold enamel, which tends to look flat and opaque. Transparent and translucent vitreous enamels are particularly stunning, allowing light to pass through the glass and reflect off the metal beneath.

Metal work: Examine the wire (in cloisonné) or carved lines (in champlevé). They should be clean, consistent, and integral to the design. Sloppy wirework or uneven carving indicates rushed or unskilled craftsmanship.

Base metal: Quality enamel jewellery typically uses fine silver, sterling silver, or gold as the base. Copper is acceptable for bowls and decorative objects. Be cautious of base metals like brass or zinc alloy, which are common in mass-produced pieces and may cause skin reactions.

Enamel Jewellery vs. Mass-Produced Alternatives

If you have ever compared a handmade enamel ring to a mass-produced "enamel" piece from a fashion retailer, you will have noticed the difference immediately. Handmade enamel jewellery uses vitreous glass fired at high temperatures, creating a permanent bond with the metal that can last centuries. Mass-produced pieces typically use cold enamel or resin that chips, peels, and discolours within months.

The colours in handmade enamel are mixed by the artisan, often in custom shades that cannot be replicated by machine. Each piece has subtle variations that make it unique. Browse our enamel jewellery collection and you will see that no two pieces are exactly alike — that is the nature of handmade art.

Caring for Your Enamel Jewellery

Vitreous enamel is remarkably durable, but like any fine jewellery it benefits from proper care. We have written a detailed enamel jewellery care guide with step-by-step instructions, but here are the essentials:

Clean your enamel pieces with warm water and a soft cloth. Avoid abrasive cleaners, ultrasonic cleaners, and harsh chemicals. While vitreous enamel resists scratching better than most materials, it is still glass — a sharp impact on a hard surface can chip it. Store enamel pieces separately from other jewellery, ideally in a soft pouch or lined box, to prevent scratches from harder gemstones or metal edges.

With basic care, vitreous enamel jewellery will maintain its brilliance indefinitely. Museum collections contain enamel pieces from the Byzantine era that still glow with the same intensity they had 1,000 years ago — that is the remarkable longevity of this material.

Enamel Bowls and Decorative Art

Enamel techniques are not limited to jewellery. Our enamelled artistic bowls use the same champlevé and cloisonné methods on a larger scale, creating functional art pieces that double as striking home décor. Each bowl is hand-carved, enamelled, and fired multiple times to build up rich layers of colour.
