The Anilite in this specimen is the material with the distinct blue reflective color. This was at first thought to be Chalcocite; but testing by George Robinson, then curator at the Seaman museum, found it be the much more rare, related species of Anilite. This is the only known location for this species in Michigan. What is quite different from other specimens from the location is the presence of both Copper and Silver in the Quartz matrix. The specimen has been coated with a two part Epoxy used for bar counter tops which has a UV inhibitor which prevents yellowing of the Epoxy.

Condition: Excellent

Flaws: Nothing Appreciable
