Black Tourmaline on Matrix with Mica - One of a Kind Specimen, 7.5 In

This black tourmaline on matrix flashes with mica every time the light shifts.

It is a raw specimen, the tourmaline still sitting in the rock it grew in, with mica scattered through, so you see the minerals the way they formed rather than cut and polished. The slab like shape lies flat or leans against books on a shelf, and the ruler photo gives the scale. It suits a mineral collector who prefers natural specimens, or someone who wants black tourmaline that looks earthy rather than polished. Tourmaline is also the October birthstone.

About Black Tourmaline

Black tourmaline, the variety called schorl, is the most common member of the tourmaline group of boron silicate minerals. Its crystals grow as long prisms, usually triangular in cross section, with heavy lengthwise striations. Mica, a sheet silicate that splits into thin, flexible flakes with a pearly to metallic luster, often grows beside it.

Stone Meaning: Black tourmaline is traditionally associated with grounding and protection.

Good to Know

• Look for fine grooves running the length of the black crystals; heavy striations are typical of schorl and help tell it from black obsidian or dyed stone.
• Low, angled light from a lamp makes the mica flash most.
