5.5" Fluorescent, Scalenohedral Calcite Crystals on Pyrite - Peru

This is a gorgeous cluster of scalenohedral (dogtooth) calcite crystals that formed from a sphalerite and pyritohedral pyrite matrix. It was collected from the Huanzala Mine in Peru and measures 5.5" wide. Under short-wave ultraviolet light, the calcite crystals fluoresce a vibrant orange-pink color.

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.
