3" Fluorescent Aragonite With Sulfur - Italy

This is a 3" wide aragonite & sulfur crystal association, collected from the Giumentaro Mine in Sicilia, Italy. What could be considered the top of the specimen, contains elongated, hexagonal aragonite crystals that display a vibrant orange fluorescence when placed under UV-lighting. Small sulfur crystal remnants can be found between these aragonite crystals. What could be considered the bottom of the specimen contains stronzianite druze.

This specimen comes with an acrylic display stand.

Aragonite is a carbonate mineral, one of the two commonly occurring crystal forms of calcium carbonate, the other form being calcite. It is formed by biological and physical processes, including precipitation from marine and freshwater environments. It's crystal lattice differs from calcite, resulting in a different crystal shape. Aragonite forms naturally in most mollusk shells, and as the calcareous endoskeleton most corals.
