Black Tourmaline Quartz Tumbled Crystal

Black Tourmaline Quartz Tumbled Crystal (shop SKU LTQT3) is offered as a tumbled stone online and at the bookshop on West 14th Street.

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.

Tumbled stones are polished in a drum, which softens sharp edges and brings out color. 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.
