Tennantite with Quartz and Chalcopyrite.
TC11Z6: Tennantite with Quartz and Chalcopyrite
Group, on a Chalcopyrite matrix, of complex Tennantite crystals with a tetrahedral shape and very rich with faces, very bright and partially coated by small Quartz crystals.

The sample is from a Mexican zone that is scarcely known in mineralogical circles, so we indicate the locality as approximate because we don’t know if all the samples are from a single mine, different mines, or from a wider mining area. We will send a copy of the analysis of the Tennantite to the buyer.
