3" Fluorescent Calcite Crystals on Pyrite - Peru

This is an incredible formation of calcite crystals on a bed of cubic pyrite crystals with striations. It comes from the Huanzala Mine in Peru and the entire specimen measures 3" wide. The calcite has a faint pink coloration to it, indicating it has trace amounts of manganese impurities. It is also extremely fluorescent under short-wave UV light, exhibiting a vibrant orange fluorescence.

It comes with an acrylic display stand.

The Huanzala mine in the Bolognesi Province of Áncash, Peru is an excellent example of a mine with exceptional quality, variety, and availability. Traditionally a lead-zinc mine, Huanzala holds the record for the most mineral tonnage extracted by a single mine. This is quite the feat and it's easy to see why minerals from this locality are so aggressively mined and collected.

This mine has a multitude of awesome minerals from sharply terminated quartz to sparkly pyrite, bubbly aragonite and dense galena. Other common minerals are realgar, orpiment, sphalerite, chalcopyrite, manganoan calcite, rhodonite, rhodochrosite, cassiterite, barite, fluorite and fluorapatite, among other less prevalent minerals. Mineral associations from this mine often contain three to four minerals at once, growing all over one another in phenomenal associations.
