Green Calcite Tumbled

This listing is for a tumbled stone, Green Calcite Tumbled (shop SKU DPGC3), which you can order online or see in the store.

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.

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: DPGC3

Look for it at Namaste Bookshop, 2 West 14th Street near Union Square, or order from the shop online.
