This exceptional Gem Silica features foundation of striking chatoyant malachite, adding a dynamic shimmer to the vivid blue silica. Colored by copper minerals like chrysocolla, Gem Silica is the rarest variety of chalcedony, known for its translucency and saturation. The Inspiration Mine, once a premier source of this material, has been mined out, making existing specimens highly collectible and increasingly scarce
This is 2nd, and last, piece of this important material that we are auctioning.
