3.4" Calcite Crystal Cluster on Pyrite - Fluorescent!
This is a cluster of pale pink manganoan (manganese-bearing) calcite crystals on a pyrite matrix from the Huanzala Mine in Áncash, Peru. Under short and long-wave UV, the calcite crystals fluoresce a vibrant pink-orange color, and even show phosphorescence.
Manganoan calcite, also known as manganocalcite, is a pink, manganese-rich variety of calcite with a chemical composition of (Ca,Mn)CO3. It crystallizes in a trigonal crystal system and forms rhombohedral or scalenohedral crystals. These crystals tend to display a pink color that ranges anywhere from pinkish-salmon to hot pink. It often displays a bright orangey-pink fluorescence under short-wave UV light.
