This specimen displays several minerals. The most obvious are transparent yellow sulfur crystals, most of do not show good crystalline form (having distorted shapes and a dull luster), although some crystals do have good vitreous faces and a near-vitrous luster. There is also quite a bit of pale blue celestite crystals present, and these, too, tend to have a dull surface, although most of them have good crystal form. The host rock also has at least two other minerals which I have not identified. The first are several prism shaped crystals, the largest of which measures about 1cm in length and is clear and colorless. The smaller crystals look like barite, so there is a good chance that these are simply more celestite but colorless and with a different habit. Lastly, there is a section on the side of the specimen that fluoresces pale yellow under LW and pale blue-white under SW UV.
