Description

Fuchsite has a Monoclinic crystal system and is the mineral class of phyllosilicates. Distinct crystals are uncommon and it is typically found in a tabular book-like form with basal planes showing a hexagonal or diamond-shaped outline. In some mica schists and quartzites, the base mineral of muscovite crystallizes with chromium impurities resulting in the emerald green colored variety of Mica called Fuchsite.

Its prism faces are striated (layered) horizontally and frequently taper. It is a very widespread and common rock forming mineral found with granites and granite pegmatites. It is also very common in metamorphic rocks, especially in mica schists where it is the most predominant mineral. Its emerald green coloring has an appearance that is usually perceived as pearly and metallic, and because of being in the Mica family it is very transparent in thin sheets and it is quite easy to rub and have tiny plates release where this would be most noticeable to the eye.
