2.35" Polished Azurite, Chrysocolla & Malachite Egg - Peru

This is a beautiful, hand-polished "egg" containing brilliant green malachite, deep blue azurite and small amounts of chrysocolla, collected from Arequipa, Peru. The lapidary work is very nice, and allows for the great, natural, botryoidal patterns in the mineral to be seen. It makes for a very aesthetic display piece. Comes with pictured display stand.

Malachite is a dark green, copper based mineral with the formula Cu2CO3(OH)2. It often forms botryoidal masses in fractures deep underground where the water table or hydrothermal fluids provide the means for chemical precipitation. It rarely forms crystals and it is often associated with another copper based mineral azurite. It was used as a mineral pigment in green paints from antiquity until about 1800.

Azurite and Malachite are known to form in union with each other, for their chemical makeup is very similar. In fact, the presence of more or less water in the location of formation, is enough to determine whether an abundance of malachite over azurite, or vise-versa, will accumulate.

These minerals tend to be found near copper deposits, which accounts for the colors the minerals display.
