Ferberite (twin on matrix)

Item Description

Here is a beautiful twinned crystal of Ferberite on rarely seen matrix. This species was sometimes previously referred to as "Wolframite", which was supposed to be an intermediary species between Ferberite and Hubnerite, but has since been discredited. This piece features the classic, "butterfly" twinning of Ferberite along the a (100) face. This twin is a sharp, lustrous, aesthetic jet-black, blocky twinned crystal measuring 2.3 cm bladed Ferberite matrix with some accenting Marcasite spheres. Twinned crystals from Bolivia have becoming increasingly difficult to obtain from Bolivia, and MATRIX specimens are virtually impossible to find! These are definitely the most highly sought after crystal habit from this locality This piece one of the most well-formed Ferberite twins that I have offered in the auctions in a long time, and the fact that its on matrix make its highly desirable. The retail value on this specimen is $1250
