FERBERITE SPECIMENFERBERITE SPECIMEN

Good weighty Ferberite 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.

Iron Tungstate FeWO4.

Ferberite belongs to a series with another mineral, Huebnerite , MnWO4.  Huebnerite is the Manganese rich end member while Ferberite is the iron rich end member.  Wolframite is the name of the series and the name applied to indistinguishable specimens and specimens intermediate between the two end members.  Most specimens found in nature fall within 20 – 80% range of the series and these are termed Wolframites, (Fe, Mn)WO4.  Only if they are 80% or more iron are they called Ferberite.  Ferberite iron content causes the dramatic differences between it and Huebnerite, Wolframite is intermediate.  Ferberite tends to be black colored, with a black streak, is opaque with a nearly submetallic luster, is denser, has crystals with a different elongation and can be weakly magnetic.  Huebnerite, however, tends to be light in color, with a lighter streak, more transparent and less dense.  Ferberite is the rarer member of the series.
