TC52C6: Bornite

This specimen merits a careful description. Bornite crystals usually tends to be small, black, ugly and not very sharp. Well, this specimen shows is colorful nature due to an iridescent alteration of a thin covering, its crystals are pretty huge and extremely sharp for the species. You can appreciate its beauty in the photo. Plus the specimen is a floater with a small Bornite crystal just on the top corner of the specimen. Just great!
