Phurcalite xls; UV-active; Utah, USA; 610 g; unique piece

Phurcalite crystals, UV-active from Utah, USA – 620 g unique piece

This 610 g specimen with Phurcalite crystals from Utah, USA, displays an exceptionally intense, widespread green fluorescence under UV light. The surface is densely covered with fine crystalline coatings that glow vividly and evenly under both shortwave and longwave UV light. The crystals form a continuous, sparkling layer across the matrix, creating an almost fully illuminated appearance in the dark. The strong uranyl-type green reaction makes this piece an impressive display specimen for any UV collection. Even in daylight, the characteristic yellowish-green tone of Phurcalite remains clearly visible.

Geology & Origin

Phurcalite is a secondary uranium mineral that forms in the oxidation zone of uranium-bearing deposits. It develops through the reaction of uranium-rich solutions with phosphate under oxidizing conditions. Utah is well known for numerous uranium occurrences where a variety of secondary uranium minerals with pronounced fluorescence can develop. The intense UV reaction is caused by the uranyl ion, which is responsible for the characteristic green glow.
