MATERIAL GUIDE
A Guide to Jewelry Plating Finishes
RHODIUM · 18K GOLD · 14K WHITE GOLD · GOLD VERMEIL
Jewelry surfaces are given a plating finish that protects the material and draws out its shine. SMUK chooses the finish best suited to each piece — rhodium, 18K gold, 14K white gold, and gold vermeil. Knowing the traits of each is the first step to enjoying your jewelry longer, and caring for it well.
Rhodium Plating
Rhodium Plating
Platinum-group hardness, with a clear, bright shine
Rhodium is a rare platinum-group metal — harder than silver and highly corrosion-resistant. Plating it over sterling silver keeps a clear, bright shine that resists tarnish for longer. Among silver tones it is especially clear and reflective. Its hard surface resists scratches, making it well-suited to everyday jewelry. It also limits the release of common allergy-causing elements, so it's a finish that considers sensitive skin.
18K Gold Plating
18K Gold Plating
A warm, rich gold shine
18K means 75% gold purity. Pure gold (24K) is too soft, so the stronger 18K is widely used in jewelry. Plating gold over a sterling silver base layers a warm color over a high-quality material. Its deep gold tone — close to 24K — sits well against the skin and suits natural and formal looks alike. Since durability varies with coating thickness, gently wiping after wear keeps the shine lasting.
14K White Gold Plating

Classic refinement, in a soft white tone
White gold is pure gold mixed with palladium and other metals; 14K indicates 58.3% purity. A white tone much like rhodium, but with a slightly warmer cast, giving a calmer, more classic impression. It pairs especially well with organic materials like pearl and with delicate designs, finishing jewelry in an elegant, formal mood. A nuance unlike either silver or gold brings a refined distinction to how you wear it.
Gold Vermeil
Gold Vermeil
A thick layer of gold, on a solid silver foundation
Gold vermeil refers to jewelry with a thick gold layer — typically 2.5 microns or more — plated over a sterling silver (925) base. What sets it apart from plain "gold plating" is that the base must be sterling silver, and the coating must meet a minimum thickness standard. The thicker gold layer is more durable than ordinary gold plating, and the shine lasts longer. Because the base is sterling silver, the quality of what touches the skin is high too. It's a finish that lets you enjoy the presence of real gold in a more accessible form.
Caring for Plated Jewelry
Care
For every finish, careful daily care is the key to keeping the shine for a long time.
- After wearing, wipe gently with a soft cloth to remove oils and sweat
- Avoid prolonged contact with water, sweat, perfume and cosmetics
- Take jewelry off when bathing, swimming or exercising
- Store pieces individually in a box or pouch to prevent friction with other jewelry
- Keep away from direct sun, heat and humidity
Knowing the material is a doorway to loving your jewelry more deeply. May that knowledge help you stay close to your piece for years to come.
