Vortex Calcite Columnar Calcite Crystal Raw

Vortex Calcite Columnar Calcite Crystal Raw (shop SKU WJVC23) is offered as a mineral specimen online and at the bookshop on West 14th Street.

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 or grade is listed.
