It comes in two grades, either containing 93.5% or 96% silver. Argentium is patented and trademarked by the Argentium Silver Company, who uses 'ARGENTIUM®' or a detailed 'flying unicorn' symbol to mark its authenticity. When hallmarked, the 93.5% grade is still classified as sterling silver and is stamped with 930.
