From: Giumentaro Mine, Caltanisetta, Sicily, Italy
Size: 7.2 x 10.5 x 4.5cm
Here's a very different type of Italian sulphur specimen from a rare location: the Giumentaro Mine. Unlike the aragonite found in other Italian sulphur mines, this one has columnar, pale-green aragonite crystals. Embedded among the aragonite crystals are a handful of small, yellow, sulphur crystals. The matrix is the regular form of white aragonite, and this specimen has growth on all sides, There is even a cavity on the left side in which more of the pale-green crystals are growing.
The extra bonus is that the green aragonite is HIGHLY fluorescent under longwave UV. It glows a very bright orange color.
The specimen comes with a labeled acrylic display base.
