RUSK COUNTY: Sphalerite is a component of the massive sulfide ore at the Flambeau deposit near Ladysmith. Occasionally it streaks reddish brown. There, sphalerite can be deposited in veins, fractures, and cavities, or it can form as mineralizations or replacements of its host rocks. When Cd, In, Ga, Ge and Ta are present, they are recovered from sphalerite as well. The chief uses for metallic zinc are in galvanizing iron, making brass, (an alloy of copper and zinc), in electric batteries, and . Sphalerite, also known as blende or zinc blende, is the major ore of zinc. These are caused by its high dispersion of 0.044. Sphalerite is the main ore of zinc and is mined throughout the world. [1] If this is not done, the owner could make a costly mistake. This lustrous SPHALERITE crystal specimen comes from the W.L. Freshly cut gems have an adamantine luster. The chemical formula of sphalerite is (Zn,Fe)S. It is a zinc sulfide containing variable amounts of iron that substitutes for zinc in the mineral lattice. Owing to their softness and fragility the gems are often left unset as collector's or museum pieces (although some have been set into pendants). Add to Wish List. It also contains galena and chalcopyrite in subordinate concentrations. It occurs in a variety of colors, and its luster ranges from nonmetallic to submetallic and resinous to adamantine. Although sphalerite has a hardness of just 3.5 to 4 on the Mohs scale and is not suitable for most jewelry use, specimens with excellent clarity are sometimes cut into gemstones for collectors. These rare elements are valuable and when abundant enough can be recovered as profitable byproducts. Names for sphalerite used in the past or by miners include "zinc blende," "blackjack," "steel jack," and "rosin jack.". Sphalerite is a mineral that is the chief ore of zinc. Uses [edit | edit source] Before deciding to cut a transparent specimen of sphalerite into a gemstone, its value as a mineral specimen should be determined. Specimens that display this distinctive cleavage are easy to identify. Dozens of countries have mines that produce sphalerite. The mineral crystallizes in the cubic crystal system. Home / Shop / Minerals / Sphalerite / Sphalerite. Since it is a very rare gemstone, you are very lucky if you can find the color you like. Specimen from the Joplin Field, Tri-State District of Missouri, USA. It is usually found in association with galena, pyrite, and other sulfides along with calcite, dolomite, and fluorite.

Like other minerals with a cubic crystal structure, sphalerite may show a tetrahedral crystal habit. Here, we use a combination of microchemical and microscopic methods to show that measurable concentrations of these elements commonly occur as atomic-scale substitutions in hydrothermal sphalerite. High-quality ones are handled as jewelry. The most common are Cd and Mn, but Gallium, Germanium and Indium may also be present in relatively high concentrations (hundreds to thousands of ppm). It is a popular stone with collectors because it has a dispersion that is three times higher than the dispersion of diamond. The darker, more opaque varieties contain more iron.
