This crystal is listed as Black Tourmaline Dolomite (shop SKU BTDO149), and is sold at Namaste Bookshop near Union Square.

Black tourmaline, or schorl, is an iron-rich tourmaline, typically opaque and striated. In crystal traditions, it is associated with protection and grounding. Those ideas belong to folklore and personal practice, not to any medical claim.

Natural stones vary in color, clarity, and shape, so the piece you receive will have its own character even when the weight, grade, or size is listed.
