13ct Peruvian Gem Silica


13.2ct Gem Silica from the Lily Mine in the Andes Mountains

18.5 x 13.2 x 8.0mm

A sizeable Gem Silica in a Stormy North Sea Blue-Green. Cut in a generously curvy, deep teardrop shape.  Clarity is opaque to translucent, some clouds present so you cannot read print through this one but it passes light.  Gem Silica is extremely durable material, having the hardness of Quartz with the superior durability of a cryptocrystalline material.  When cut en cabochon, very suited for daily wear rings, bracelets, and pendants.   I have observed no hygroscopicity on this piece so I expect it will keep it’s translucency in most any environment.
