Great Ferberite Quartz Specimen to add to your collection. An uncommon metal Crystal in a double terminated Quartz Crystal. The Ferberite Crystal has a partial termination on top. 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.
