Gem Silica Slabs & Cabochons

Gem silica is chrysocolla and related copper minerals in their rarest form, silicified into hard, translucent quartz. Supply is genuinely limited. A small number of historic mines, including Inspiration Mine and Ray Mine in Arizona, produce most of the fine material available, alongside Peruvian gem silica from South America.

Our collection features Peruvian gem silica, Inspiration Mine gem silica, and Ray Mine gem silica, along with Quantum Quattro material. Every piece is selected for color saturation and clarity.
