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.
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.
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.
