Though very small, this specimen comes from a relatively unknown American locality for Sulfur, and shows at least 7 incomplete but well-formed crystals that are intergrown. The largest of these shows visible dimensions of 0.6 x 0.4 x 0.3" (1.5 x 1.0 x 0.8 cm), and like the others, shows excellent orthorombic pyramidal form, with well-defined edges and clean faces that show a bright, nearly vitreous luster. All have a moderate yellow color and are transparent, though their intergrowth and many internal fractures spoil their clarity. There is no host rock or any other foreign material present. It would appear that the specimen is attached to the foam base of the specimen box with a soft putty; the piece could be carefully detached for display in another box or on a small base.
