1.59" Beryl Emerald in Quartz & Biotite - Bahia, Brazil
This is a dark green beryl emerald from Bahia, Brazil. This 1.59" long emerald crystal is surrounded by milky quartz and biotite. Three separate emeralds can be found around the specimen, with the largest emerald reaching from one end of the specimen to the other.
Beryl is a mineral composed of beryllium aluminum cyclosilicate, with the chemical formula Be3Al2(SiO3)6. Naturally occurring beryl tends to form hexagonal crystals that can reach several meters in size if given the right conditions. Completely pure beryl will be transparent and colorless, while mineral impurities frequently tint the crystals color in most specimens.
Well known varieties of beryl include aquamarine and emerald, although beryl can also be green, blue, yellow, white and red, depending on the incorporated impurities during formation. Red beryl is its rarest form, and can currently only be found in New Mexico and Utah.
