Several partly intergrown native Sulfur crystals rest on the calcareous host rock of this small hand specimen. The crystals range in size from a few millimeters along each axis to 1.3 x 0.8 x 0.7" (3.3 x 2.0 x 2.8 cm), and most are either damaged or broken and incomplete. The largest crystal is the most complete of the lot, and shows the best orthorhombic prismatic form where intact- its edges are quite well-defined, and its faces are clean and possess the standard pearly-to-vitreous luster. All have the classic bright yellow of Sulfur, and they are generally transparent, though all are heavily internally-fractured. The base rock on which they rest is made up primarily of many tiny, intergrown calcite scalenohedra, but there is also some brown material that might simply be more, dirty calcite.
