Description

Wonderful example of this extremely rare mineral. There is a bright plate of quartz on which the silver shiny sylvanite crystals grow. They have an interresting texture, thats why it was also named "letter ore" by the swiss mineralogist Abraham Gottlob Werner. The origin of the name sylvanite comes from the old name of the area it is found: Transylvania.
