Item Description

Here is a wonderful display specimen of crystallized Ferberite. 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, thick, lustrous, sharp, jet-black, "built-up" bladed crystals forming an attractive group free of matrix. The largest blade measures 2.8 cm across. Overall the piece is in good shape, but it does have a few contacted crystals and some rough edges around the periphery were it detached from the pocket wall. It has become increasingly difficult to obtain fine quality crystallized Ferberites from Tasna these days and nearly everything is thrown into the crusther for the value of the tungsten ore. This piece is actually from an older find in 2013, and stands out as one of the best cabinet sized dipslay specimens that I've had to offer in the auctions in quite some time. If you've ever wanted a good Ferberite from this famous mine that won't break the bank, don't miss out on this one. Valued at $1,500 in the inventory, were it 100% perfect, I could easily see it priced at $3k+. PLEASE NOTE: This specimen is fairly heavy, and will require an additional shipping charge.
