Red/orange colored Wulfenite crystals which are partially coated with snow white colored, druze Calcite. The Wulfenite crystals have a high, sparkly luster. Of particular note on this specimen, is the area where the layer of white Calcite and Wulfenite is missing. This rounded area appears to have an underlying layer of yellow colored crystals with a thin, partial layer of darker material with a submetallic luster. It is unclear what either of these materials are. The only other species listed on mindat for the location is Cerussite. Additionally, the matrix is composed of a black material with areas of white. On the bottom of the specimen, under magnification, some of the white material appears to be micro crystals of Quartz. There are also micro black crystals on the surface which fluoresce an orange color and are likely Calcite. The black material remains a mystery. The overall weight of the specimens is relatively heavy for its size.

Condition: Very Good

Flaws: Nothing Appreciable
