2.8" Garnets with Calcite, Epidote, Mica & Feldspar - Pakistan

 
This garnet centered specimen comes from a location in Pakistan, where associations of deep orange/brown garnets, feldspar, golden mica, green epidote, and calcite are typically found. The garnets from this location display a unique pattern, which can be seen along the faces of the crystals when rotated under light.

This specimen contains the entire variety; garnets, calcite, epidote, mica and feldspar, all clustered on a feldspar matrix. Most of the green epidote that's visible is either smaller, or laying against the minerals below, giving the epidote an opaque appearance. The garnets can be found clustered throughout grouping of minerals, with crystals ranging anywhere from speck to dime sized. The mica accounts for the small golden colored flakes that can be found scattered around the specimen.

Garnets are nesosilicates having the general formula X3Y2(Si O4)3. There are many species of garnet which are pyrope, almandine, spessartine, uvarovite, andradite and grossular (varieties of which are hessonite or cinnamon-stone and tsavorite).

Garnet species are found in many colors including red, orange, yellow, green, purple, brown, blue, black, pink, and colorless, with reddish shades most common.

Spessartine, often mistakenly referred to as spessartite, is a nesosilicate, manganese aluminium garnet species, Mn2+3Al2(SiO4)3. The name is a derivative of Spessart in Bavaria, Germany, the type locality of the mineral.
