2.2" Garnet Cluster with Black Tourmaline (Schorl) - Pakistan

This garnet centered specimen comes from a location in Pakistan, where associations of deep orange/brown garnets, feldspar, golden mica, green epidote, black tourmaline 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. One edge of the specimen contains an aggregation of black tourmaline (schorl) crystals.

Tourmaline is a crystalline boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Schorl, or black tourmaline, is the most common form of tourmaline, and has been used for everything from jewelry to piezoelectric guitar pickups.

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.
