Natural Terminated Black Tourmaline Crystal – Gerais, Minas, Brazil – 0.14 lbs

This naturally terminated Black Tourmaline crystal from Minas Gerais, Brazil, displays the classic elongated prismatic habit and strong vertical striations that have made Brazilian tourmaline a favorite among mineral collectors. Preserved with its natural termination intact, this specimen showcases the crystal's original growth form without cutting or polishing.

The sharply defined prism faces exhibit the characteristic longitudinal grooves of schorl (black tourmaline), while the intact termination provides an authentic view of the crystal's final stage of growth. Rich black luster and excellent structural preservation make this a beautiful display specimen despite its compact size.

Collected from the world-renowned pegmatite districts of Minas Gerais, this crystal represents one of the classic localities for high-quality tourmaline specimens.

About Black Tourmaline

Black Tourmaline, the iron-rich variety known as schorl, is the most abundant member of the tourmaline group. It commonly forms within granite pegmatites and hydrothermal environments, where mineral-rich fluids allow crystals to develop their distinctive elongated prisms and naturally striated surfaces.

Minas Gerais, Brazil, is among the world's premier sources for tourmaline, producing exceptional crystals prized for their well-defined crystal habits and mineralogical significance. Naturally terminated examples are especially desirable because they preserve the crystal's original growth features exactly as they formed in nature.

The vertical striations seen on the crystal faces are a hallmark of tourmaline and serve as one of its most recognizable identifying characteristics.
