Emerald Specimens On Mica Schist

This mineral specimen is listed as Emerald Specimens On Mica Schist (shop SKU EMS16), and is sold at Namaste Bookshop near Union Square.

Emerald is the green variety of beryl (beryllium aluminum silicate), colored by chromium or vanadium, and is sometimes found in mica schist. These are mineral specimens as described on the listing, not faceted gemstones unless the title says otherwise. In crystal traditions, emerald is associated with the heart. Those ideas belong to folklore and personal practice, not to any medical claim.

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: EMS16
