FERBERITE MINERAL SPECIMEN
Awesome Specimen with minor Quartz to add to your collection. An uncommon metal Crystal showing good terminations and classic striated faces. The Ferberite Crystal has a few small Quartz Crystals penetrating the side faces. Ferberite is an ore of Tungsten. Tungsten is used to fake Gold bars coated with a thin layer of real Gold. That is because Tungsten has the same specific gravity as gold does. The best way to test for this type of fakery is to drill a very small hole in the bar. Thus the specimen feels heavy to hold just like Gold.
