WHAT IS 925 STERLING SILVER?

925 Sterling Silver is an alloy of silver containing 92.5% pure silver and 7.5% other metals, usually copper. Fine silver (99.9% pure) is generally too soft for producing large functional objects, and in Sterling Silver, the silver is usually alloyed with copper to give strength whilst preserving the malleability of the silver and a high precious metal content – ideal for making silver jewellery

Other metals can replace the copper, usually with the intent to improve various properties of the basic sterling alloy such as reducing casting porosity, eliminating firescale (a red or purple stain), and increasing resistance to tarnish. These replacement metals include germanium, zinc, and platinum, as well as a variety of other additives including silicon and boron.

 

GOLD PURITY

Pure gold, 24kt, is exceptionally soft and not suitable for jewellery making. Alloy metals used give pure gold stability so that it can be made into beautiful lasting jewelry. Beyond the strengthening purpose, alloying allows for colored gold. The most common colors of gold today are white gold and rose gold.

Notes:

The alloying metal compositions above are typical of those used by the jewellery industry to arrive at the colour/caratage combinations shown, but these are not the only ways to arrive at these combinations.

White gold compositions listed here are nickel free. Nickel-containing white gold alloys form a small/very small percentage of white gold alloys and generally contain other base metals such as copper and zinc.
