Ruby Fuchsite / Ruby in Fuchsite

Hardness: 7-7.5 (Mohs scale, for quartz), Color: Pink/red (fuchsite), green (chromium-rich mica), white/clear (quartz), Luster: Vitreous (quartz), pearly/silky (fuchsite), Crystal structure: Trigonal (quartz), monoclinic (fuchsite)

Ruby fuchsite is typically formed in metamorphic environments where chromium-rich magmas or fluids interact with aluminum-rich rocks. The fuchsite (green mica) develops under regional metamorphism, while rubies (a variety of corundum) also form during metamorphic processes under high pressure and temperature conditions. The geological age can vary depending on the specific deposit, but it's often found in ancient metamorphic belts.

Primarily used as an ornamental stone for carvings, spheres, and decorative objects. It is also popular in the lapidary arts for cabochons and tumbled stones in jewelry.

Fuchsite is often used in ornamental carvings and often confused with jade due to its similar green color. The vibrant color of fuchsite comes from the presence of chromium.

Field identification often involves observing the distinct color contrast between the pink/red ruby crystals and the vibrant green fuchsite, often within a white or grey quartz matrix. Its relatively high hardness helps distinguish it from softer minerals. Common locations include India and Brazil.
