Ruby Crystal Tumbled

Ruby Crystal Tumbled is a tumbled stone (shop SKU HSRB1) on the shelves at Namaste Bookshop in Manhattan.

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: HSRB1
