Gem Silica from Inspiration Mine, Arizona. This vibrant blue-green gemstone owes its striking color to copper impurities within its silica structure. As a variety of chalcedony, Gem Silica forms through the gradual deposition of silica-rich fluids in copper-rich environments, resulting in its highly saturated hue and smooth translucence. Material from the historic Inspiration Mine is considered some of the finest ever discovered, prized for its intense color and clarity. Rare and highly sought after, it remains a cornerstone in fine gemstone collections.
