❥Sterling silver is an alloy of pure silver containing 92.5% (925 stamp) by weight of silver and 7.5% by weight of other metals, usually copper. Pure silver is a soft metal which needs a mix of other metals to strengthen it. The sterling silver standard has a minimum millesimal fineness of 925.
❥Vermeil gold is a specific kind of gold plating. The process of creating a vermeil piece of jewelry involves coating sterling silver 925 base with a thin layer of real gold that is at least 10 karats and 2.5 microns thick.
❥Rhodium is a fine metal, just like gold or platinum, and is a member of the platinum family of metals. It has a bright, silvery-white appearance and is naturally corrosion resistant. While rhodium is both too expensive and too brittle to make jewelry out of, it makes an excellent plating material. Rhodium is very rare as it is never found as a single mineral hence is more expensive than gold,silver and platinum. It is cultivated in very small quantities within nickel and platinum ores. Its purity also makes it hypoallergenic.
