Raw Black Tourmaline Crystal
This is a specimen of raw black tourmaline, also known as Schorl. The item exhibits the characteristic trigonal crystal system typical of the species, displaying prominent vertical striations and a vitreous to sub-metallic luster on its various faces. Geometrically, it is an irregular, chunky block approximately 2 to 3 inches in length. Its color is a deep, opaque jet-black. The texture is markedly rugged and crystalline, showing significant fragmentation and natural fracturing along the grain. Fine white or light-colored mineral inclusions or surface dust are visible within the crevices, providing a sharp contrast to the dark core. The condition appears to be strictly raw and unpolished, with sharp, jagged edges and no evidence of human craftsmanship or mechanical tumble-finishing. This specimen likely originates from a pegmatite formation. There are no maker's marks, as it is a natural mineral specimen. The quality represents a standard cabinet-grade specimen often used for decorative purposes or by collectors of metaphysical stones. Natural wear includes surface crumbling and small crystalline chips common to tourmaline's brittle nature.
