Black Tourmaline Dolomite

Among the books, decks, and stones on 14th Street is this crystal: Black Tourmaline Dolomite (shop SKU SKBT36).

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.
