Good weighty Specimen for your collection. Good Aussie metal specimen of an uncommon mineral. Ferberite is an ore of Tungsten which is used to create fake Gold bars which are then coated with a thin layer of 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 and test the filings. This specimen is mounted on a perspex pad for enhanced display.
