This Italian classic can be hard to come by, especially in this size and quality. The Giumentaro Mine was a famous Sicilian sulphur mine that ceased operations in 1984. This specimen boasts some very sharp intergrown elongated hexagonal crystals, with a faded green hue and a high luster. There is also a bit of Sulphur on the matrix as an added bonus.
Under short wave UV the specimen fluoresces a strong orange-pink, after the UV is turned off the specimen displays bright green phosphorescence as it fades back to normal. Under long wave UV the specimen exhibits a bright blue-white fluorescence.
The specimen is in great condition and an excellent example for your cabinet.
