Phurcalite xls; UV-active; Utah, USA; 436 g; unique piece

Phurcalite crystals, UV-active from Utah, USA – 436 g unique piece

This 436 g specimen with Phurcalite crystals from Utah, USA, displays a fine crystalline, surface-covering formation in yellowish-green to intensely luminous tones. The crystals evenly coat the matrix and create a dense, vividly textured surface with an attractive color distribution. Under UV light, the specimen reveals an impressive, strong green fluorescence that appears widespread and uniform. The crystals respond clearly under both shortwave and longwave UV light, producing a striking visual contrast against the matrix. A very appealing collector’s piece with pronounced UV performance.

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.
