Down inside a cast of fossil coral is a cluster of Sphalerite crystals with a very attractive iridescence. Underneath the iridescence, the crystals are a gemmy orangish color. The Sphalerite crystals are dusted with very small, micro crystals of Chalcopyrite. There are some additional, smaller crystals which have less of the iridescence making the orange color more pronounced and are quite transparent. Some of these crystals have an elongated habit unusual for Sphalerite. The location is a working quarry about an hour outside of Toronto. However, collecting is only allowed twice a year through the Central Canadian Federation of Mineralogical Societies. This is the best Sphalerite specimen I have seen from the location.

Condition: Excellent

Flaws: Nothing Appreciable
