Great looking Metal Specimen of Huebnerite Quartz Crystals, showing amazing crystal formations protruding out of the interlacing quartz matrix. This is a very collectable piece. Huebnerite is an ore of Tungsten. Tungsten is used to make fake Gold bars. 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.
