Tennantite with Quartz and Chalcopyrite
 

TD60Z6: 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 analysis of the crystals indicates that they are basically silvery Tennantite, but the presence of other silver minerals such as Miargyrite, Pyrargyrite or Freibergite has been detected. 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.

This kind of Opal (variety hyalite), in addition to the fact that it is gemmy and quite aesthetic, standing up on its matrix, has the extraordinary property of fluorescing in daylight! In fact, it fluoresces in almost all types of light, neon light, LED light, daylight and, of course, UV light. The only light with which it doesn’t react is incandescent. As they are so new the locality is still very vague, sorry for that, but we are sure that time will clarify the locality as well as the reason why they fluoresce so strongly.
