Vortex Calcite Columnar Circle

This crystal is listed as Vortex Calcite Columnar Circle (shop SKU WJVC79), and is sold at Namaste Bookshop near Union Square.

Calcite is calcium carbonate, a soft mineral that can form in many colors and crystal habits, including columnar 'vortex' shapes. Because it is soft, it is best kept dry and handled gently.

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.
