Ruby Kyanite Tumbled Crystal

Ruby Kyanite Tumbled Crystal (shop SKU HSKTR3) is offered as a tumbled stone online and at the bookshop on West 14th Street.

Kyanite is an aluminum silicate that typically forms bladed crystals, often in blue. It has two hardnesses depending on direction and should be set and worn with care.

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.
