Euhedral crystals – occurs as well-formed crystals showing good external form. Sale! sphalerite (sfăl`ərīt, sfā`–), mineral composed of zinc sulfide, usually containing some iron and a little cadmium.It occurs in crystals of the isometric system but more generally in cleavable, compact masses. One of the most distinctive properties of sphalerite is its cleavage. It also contains galena and chalcopyrite in subordinate concentrations. The iron content is normally less than 25% by weight. This is because it looks a lot like Galena, only it does not contain lead, much to the disappointment of early miners. Sphalerite is named after Greek word for "mistaken", because the mineral was often mistaken for galena, but contained no lead. When mined, it drops Sphalerite Dust, with a little chance to get Zinc Dust and a lesser chance to get a Yellow Garnet, which can be processed in an Industrial Electrolyzer to receive one Zinc Dust and one Sulfur Dust. It consists largely of zinc sulfide in crystalline form. Sphalerite, an ore of Zinc. The structure is closely related to the structure of diamond. Sphalerite is the principle ore of zinc. When iron content is high it is an opaque black variety, marmatite. The best way to learn about minerals is to study with a collection of small specimens that you can handle, examine, and observe their properties. Sphalerite's very low hardness (3.5 to 4 on the Mohs scale) and perfect cleavage make the mineral a very poor choice for any jewelry except pieces such as earrings and brooches that will receive very little abrasion or impact. It consists largely of zinc sulfide in crystalline form but almost always contains variable iron. 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. If this is not done, the owner could make a costly mistake. It is also known as Blende or Zinc Blende, and is the major ore of zinc. Zinc is used in protective zinc-coatings on steel, in brass (copper-zinc alloy) production, in batteries and electronics and in the production of white pigment (ZnO - zinc oxide). Mineral specimens. Polishing scratches on the bottoms of sphalerite cabochons may cause apparent chatoyancy and asterism. Further, this crystal is an essential ore and it is commonly found in a hydrothermal vein.

It is a popular stone with collectors because it has a dispersion that is three times higher than the dispersion of diamond. [5] The abundances of these elements are controlled by the conditions under which the sphalerite formed, most importantly formation temperature and fluid composition.[5]. However, due to its variable trace element content, sphalerite is also an important source of several other elements, such as cadmium,[6], gallium[7] germanium,[8] and indium.[9]. The amount of iron substitution that occurs depends upon iron availability and temperature, with higher temperatures favoring higher iron content.
