Malachite
This sample comes to us from Cove Mine Bisbee, Arizona.  

Malachite is a green copper carbonate hydroxide mineral with a chemical composition of Cu2(CO3)(OH)2.  The FOV here is 5.5mm.

This was captured with 105mm Sigma on 1.4x converter and 136mm of extension.  I think I will revisit it with a 10x objective when I can.
