Malachite

Malachite, Cu2CO3(OH)2 (Copper Carbonate Hydroxide), is a well known and popular semi-precious stone and is named after the Greek word for "mallow", a green herb. The banded light and dark green designs give it a unique ornamental quality unlike that of any other stone. The bands and colour are so distinctive that Malachite is one of the most easily recognised minerals by the general public.

Description: A triangular matrix on which sits a crust of Malachite. Although the blanket is mostly amorphous, several crystalline botryoidal masses can be seen under modest magnification. The luster is earthy and shows off the rather unusual green colouration.

Location: Wheal Unity, Gwennap, Cornwall, England.
