Calcite on Sphalerite With Fluorite
Gibraltar Mine, Naica, Chihuahua, Mexico
Cabinet, 10.6 x 8.0 x 5.5 cm
A beautiful combo piece of bright white calcite covered with a second generation of sparklier, minutely-crystallized calcite, perched on bright jet-black sphalerite crystals. very sparkly and colorful overall for a black-and-white piece. Small, gemmy, transparent cuboctohedral fluorites sprinkle the calcite at its tip and are scattered about the matrix as well. I am told that not many of these came out with the main pocket of fluorites.
