  • SYLVANITE (Silver Gold Telluride) Galleries

    To be an actual significant part of a non-alloyed mineral is really quite uncommon for gold and this makes sylvanite a unique mineral indeed. For some reason gold has an affinity for the element tellurium, which is sometimes found naturally as native tellurium. Tellurium is a semi-metallic element which means that it has some properties of metals but not all or as strongly.
