Jewelry metals compared

Understand what you are paying for. Here is how the common jewelry metals stack up on durability and cost.

MetalWhat it isDurability
Gold VermeilSterling silver coated with a thick layer of gold (at least 2.5 microns) over a 10k-or-higher base.Good for occasional wear; the gold layer can wear over years of daily use.
Gold-FilledA thick bonded layer of gold (typically 5% of total weight) over a brass core, more durable than plating.Very good; lasts years with care and resists tarnish better than vermeil.
Gold-PlatedA thin micron layer of gold over a base metal, the most affordable gold-look option.Limited; the thin layer wears and fades faster than vermeil or gold-filled.
Solid Gold (10k to 18k)Gold alloyed with other metals throughout, sold by karat. The most durable and valuable option.Excellent; a lifetime piece that holds value and resists tarnish.
Sterling Silver (925)92.5% silver alloyed with copper, the standard for fine silver jewelry.Good; tarnishes over time but polishes back, and is easy to maintain.
