Sterling silver is a popular alloy in jewellery making, which comprises a mixture of 92.5% pure silver with 7.5% made up of other alloys, usually copper.
Argentium however, contains a greater amount of pure silver depending on the grade (935 which contains 93.5% pure silver), with the remainder being made up of other alloys, such as a small amount of germanium.
This unique addition of germanium gives Argentium silver beneficial attributes such as fire stain resistance, improved durability & also a higher melting point, which translates to a higher annealing temperature & flow point.
