Jewellery Plating Guide | Rhodium, 18K Gold, 14K White Gold & Gold Vermeil Explained
A Guide to Jewelry Plating Finishes
Rhodium · 18K Gold · 14K White Gold · Gold Vermeil
Every piece of jewelry is finished with a plating chosen to protect the metal and bring out its finest qualities. At SMUK, we select the most suitable finish for each piece. Rhodium, 18K gold, 14K white gold, and gold vermeil — understanding the difference is the first step to wearing and caring for your jewelry with intention.
Rhodium Plating
The hardness of the platinum group, with a luminous clarity.
Rhodium is a rare member of the platinum family — harder than silver and highly resistant to corrosion. When applied over sterling silver, it creates a bright, crisp finish that resists tarnish far longer than uncoated silver.
Among silver-toned finishes, rhodium stands out for its exceptional clarity and light reflectivity. Its hardness also makes it more resistant to everyday scratches, making it well-suited for daily wear. For those with sensitive skin, rhodium plating acts as a protective barrier, reducing the risk of irritation from the base metal.
18K Gold Plating
Warm, rich gold with a quality foundation.
18K indicates a gold purity of 75%. Pure gold (24K) is too soft for everyday wear, so 18K — alloyed for strength — is the standard for fine jewelry. Applied over a sterling silver base, it layers a warm, radiant gold tone over a high-quality foundation.
The result is a deep, luminous gold color that flatters a wide range of skin tones, transitioning effortlessly from casual to formal. The longevity of the finish depends on the thickness of the plating, so a gentle wipe after wearing goes a long way in preserving its glow.
14K White Gold Plating
Classic refinement in a softly cool white.
White gold is created by alloying pure gold with metals such as palladium, resulting in a cooler, silvery tone. At 14K, the gold content is 58.3%. While similar in color to rhodium, white gold carries a subtly warmer undertone — quieter and more classic in its feel.
This finish pairs particularly well with organic materials like pearls and delicate designs, lending them an elegant, timeless quality. It occupies its own space between silver and gold — nuanced, refined, and quietly distinctive in any setting.
Gold Vermeil
A thicker gold layer, built on a sterling silver foundation.
Gold vermeil (pronounced ver-may) refers specifically to sterling silver (925) coated with a layer of gold at least 2.5 microns thick. What sets it apart from standard gold plating is the quality of both the base — sterling silver — and the depth of the gold layer itself.
A thicker coating means greater durability and a longer-lasting shine compared to conventional gold plating. With sterling silver at its core, the part of the piece that touches your skin is held to a higher standard. Gold vermeil offers the presence of real gold in a form that is both beautiful and accessible.
How to Care for Plated Jewelry
Whichever finish you choose, a little daily care goes a long way in preserving its beauty.
- After wearing, gently wipe with a soft cloth to remove oils and perspiration
- Avoid prolonged contact with water, sweat, perfume, and cosmetics
- Remove before bathing, swimming, or exercising
- Store each piece individually in a pouch or box to prevent scratching against other jewelry
- Keep away from direct sunlight, heat, and humidity
To know your materials is to love your jewelry more deeply.
