This Sicilian specimen consists of a few Sulfur crystals that rest on a base of pale brown, chalky host rock. Though most of the crystals on the specimen are damaged and incomplete, those that are intact are in very good condition and have excellent, if odd, form. The largest crystal has visible dimensions of 1.1 x 0.7 x 0.5" (2.8 x 1.8 x 1.3 cm), and shows partial damage and two large cracks running through it. It appears to be in the form of a trigonal bipyramid that is laying down on one side, and does not resemble the orthorombic form that Sulfur usually possesses. Another crystal has an even stranger form, as it appears that one of its sides forms a gentle, continuous arc that spans nearly 90 degrees. A third crystal appears to consist of a single orthorombic pyramid. All of these crystals have the bright yellow color of Sulfur and a waxy-to-pearly luster. They show dim transparence in some areas, though the dull luster prevents one from clearly seeing their interiors. These crystals rest on a bed of pale gray celestite that shows some crystal form, though it is severely warped. The few crystalline areas show a pearly luster and are transparent and moderately clear. There is a sizable patch of Sulfur on the opposite side of the specimen, but this consists of a badly broken cluster, and there is almost no discernable crystal form. The larger crystal's color is unusually deep, and has an orange tint to it.
