Gem silica, also known as "chrysocolla chalcedony" or "chrysocolla in chalcedony," is a rare and valuable form of chalcedony, which is a type of microcrystalline quartz. What makes gem silica so prized is its vivid blue to greenish-blue color, which is caused by the presence of copper. It is often translucent and can exhibit a waxy or vitreous luster.

Gem silica is highly sought after by collectors and jewelry enthusiasts for its beautiful color and relative rarity. It is used in the creation of high-end jewelry pieces, including rings, pendants, and earrings. Due to its scarcity, gem silica can be quite expensive, especially when it exhibits a deep, uniform color and is free of impurities.
