4.5" Aquamarine & Muscovite Cluster - Pakistan

This is a beautiful specimen that contains an association of sky-blue aquamarine crystal clusters with muscovite, from Baltistan, Pakistan. The specimen features several lustrous, aquamarine beryl crystals that have formed in association with muscovite crystals. The entire specimen is 4.5" long by 3" wide.

Beryl is a mineral that's 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 known to be the most rare form of beryl found and is currently only known to be found in New Mexico and Utah.

Muscovite is a phyllosilicate mineral of aluminium and potassium. It has a highly perfect basal cleavage yielding remarkably thin laminae which are often highly elastic.
