Phurcalite xls; UV-active; Utah, USA; 280 g; unique piece

Phurcalite crystals, UV-active from Utah, USA – 280 g unique piece

This 280 g specimen with Phurcalite crystals from Utah, USA, displays a fine crystalline, surface-covering formation in intense yellowish-green tones. The crystals densely and evenly coat the matrix, creating a vividly textured surface with clear color zoning. Under UV light, the specimen reveals a strong, bright green fluorescence that extends across the crystal-covered areas. The reaction is clearly visible under both shortwave and longwave UV, producing a striking visual effect in a darkened setting. A highly attractive collector’s piece with pronounced UV performance and intense luminosity.

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.
