Ferberite (twin)

Item Description

Here we have a wonderful example of twinned Ferberite from this renowned Tasna Mine in Bolivia. The twinned Ferberites from this mine are the best examples of the material in the world. Ferberite was sometimes previously referred to as "Wolframite", which was supposed to be an intermediary species between Ferberite and Hubnerite, but has since been discredited. Here is a wonderful miniature sized twinned crystal of featuring the classic, "butterfly" twinning habit along the a (100) face of the crystals creating a fine quality, sharp, lustrous, stout, aesthetic jet-black twin that is displayable from a few angles. It is virtually damage free on the display side, but it is contacted underneath where it was separated from the pocket wall. It's very hard to get fine quality, undamaged twins of Ferberite from any locality, as Tasna is no exception. Twinned Ferberite crystals from this mine have becoming increasingly difficult for me to obtain, as the miners do not take care of the crystals, so they're almost always dinged or cleaved. In addition, the price of tungsten can cause superb twinned crystals to be thrown into the crusher and destroyed for the mere value of their ore. These are definitely the most highly sought after crystal habit from this locality, and highly sought after by collectors. This piece one of the most well-formed Ferberite twins that I have had to offer in the auctions in a while, and would make a great addition to any collection. Priced in the inventory at $1,500.
