2.3" Striking Sulfur Crystals on Fluorescent Aragonite - Italy

This is a 2.3" wide specimen of sulfur crystals associated with aragonite, collected from the Cianciana Mine in Sicilia, Italy. The crystals have a ridiculously vibrant color and are in a solid habit instead of as a powdery coating typical in sulfur deposits. This specimen has been mounted to a clear acrylic display stand with mineral tack for a clean, aesthetic presentation.

Under shortwave ultraviolet light, the aragonite exhibits a vibrant orange-pink fluorescence.

The chemical composition of this vibrant mineral is S8, eight sulfur atoms bonded together to form a sulfur molecule. The crystal structures are typically tabular or blocky dipyramids that form in sedimentary rock.

One note on handling: sulfur crystals can crack when exposed to rapid changes in temperature.
