Because of its softness (Mohs hardness 4.5-5.0), scheelite (Calcium tungstate) is strictly a collector's gem. It is unsuitable for use in jewelry. Although very soft, some scheelite does possess a beautiful deep golden color that complements a high refractive index (1.918-1.934). Like other soft gem materials, scheelite is difficult to polish and presents a considerable challenge for a gem cutter. When purchasing a faceted scheelite, look for sharp, well-defined facet junctions (not rounded edges) and a polish free of scratches. Facet grade scheelite occurs in seveal world locations, but China is currently producing the deep golden-colored material shown above. The image presented above is not a perfect reflection of the true color of the gem. It is actually a more uniform medium dark golden color. The brighter flashes of reflected light caused overexposure in the original photograph. The above exceptionally well crafted gemstone is of the finest deep golden colored scheelite coming from China. This gem is arguably one of the finest faceted scheelites currently on the gem market. It would be a beautiful addition to any gemstone collection.
