Ruby IN Granite Tumbled Crystal

Ruby IN Granite Tumbled Crystal (shop SKU RMRG3) is offered as a tumbled stone online and at the bookshop on West 14th Street.

Ruby is the red variety of corundum, a very hard gem mineral. In crystal traditions, ruby is associated with vitality and devotion. 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.

• SKU: RMRG3

You can see this one in person at Namaste Bookshop, 2 West 14th Street near Union Square in New York City, or order it online.
