Metal Plating

What is Sterling Silver?
Pure silver, also referred to as fine silver, has an actual silver content of 99.9%. Because of its high purity, fine silver is too soft for use in jewellery-making and needs to be mixed with other metals to make it harder.

The alloy Sterling Silver, as we know it, has a minimum millesimal fineness of 925, and became the unified Standard of Silver, adopted internationally, in 1868. The alloy contains 92.5% by weight of silver and 7.5% by weight of other metals usually copper - although zinc, platinum or germanium are also commonly used. The 92.5% of silver content in Sterling Silver is why it is commonly referred to as Silver 925 or 925 Silver.

A hallmark or assay is the official mark / stamp struck on items made of metal - mostly to certify the content of noble metals—such as platinum, gold, silver and in some cases, palladium. In a more general sense, the term hallmark can also be used to refer to any distinguishing characteristic. It is not always that easy to differentiate 925 jewellery from other silver products. For this purpose stamps are used. Sterling Silver jewellery is hallmarked 925 or S925.
A technique used by Silversmiths to prevent tarnishing is jewellery E-coating. Also known as Electro-coating or Electro deposition. It is a method that uses electrical current to coat a metal surface with an organic lacquer, covering every nook and cranny on the jewellery with an even and consistent protective coat. The coating does not chemically alter the base metal upon which it is deposited. These coatings come in a variety of colours and finishes and their length of effectiveness and durability varies and is hugely determined by the actual wear and care of the jewellery.
