Deep Green Conichalcite Heavily Including Calcite on limonite matrix 2 sided Mineral Specimen

Dimensions (mm): 55 x 45 x 22

Dimensions (inches): 2.2 x 1.8 x .9

mined in Mexico in the 1980's at Mina Ojuela , Mapimi
Conichalcite is a copper mineral (CaCu(AsO4)(OH))

When mineral people say including they mean that one mineral formed inside the other. Here the normally white calcite crystals are green because the conichalcite grew inside coincidentally. We sent a specimen to the lab to find out that the green was conichalcite

All Mineral Specimens come with a label with the name of the mineral and where it was mined

We prefer natural gemstones and only rarely sell enhanced gemstones. If the stone is enhanced we clearly state the enhancement in the listing ad.

I do my best to describe all items accurately and will point out notable defects and flaws, however, due to the nature of natural stones I may miss minute flaws. Please do not hesitate to ask

Some gemstones prefer not to be constantly exposed to direct sunlight, please ask.

Please ask about cleaning instructions. Different minerals require different care. Please never plunge a crystal into very hot or very cold water, the sudden temperature change can be damaging
