Tetrahedrite (silver rich variety) with Chalcopyrite and Quartz.
MB91AG1: Tetrahedrite (silver rich variety) with Chalcopyrite and Quartz
This elegant silver-rich Tetrahedrite with Chalcopyrite and Quartz has a long history with labels starting in 1925 by Franz Ding and ending with John S. White. At that time the silver-rich Tetrahedrite was called "Freibergite", that name has come with the label but an analysis have proven that it is not "Freibergite" but silver-rich Tetrahedrite. Although the photos may look like there is a broken crystal the piece is perfect and has no damage. We will send labels and the analysis to the buyer of the specimen.

Tetrahedrite (Subgroup) with Bournonite and Siderite.

The piece as a whole continues to display well because the rest of the crystals are healthy and the break is hidden towards the back, but it has that defect, which the price takes into account.
