Minor amounts of manganese and arsenic can also be present in sphalerite. Sphalerite (which is also known as Blende), is an important ore of zinc and can make a rather attractive cabinet specimen as well. RUSK COUNTY: Sphalerite is a component of the massive sulfide ore at the Flambeau deposit near Ladysmith. Diamond is well known for its exceptional "fire" - flashes of color as the gem is moved under a source of light. Sphalerite is also found in veins an… Sphalerite is a significant zinc ore … Since sphalerite ranks as the primary ore for zinc mining, scientists have synthesized this mineral for industrial research. Gemmy, pale specimens from Franklin, New Jersey (see Franklin Furnace), are highly fluorescent orange and/or blue under longwave ultraviolet light and are known as cleiophane, an almost pure ZnS variety. Sphalerite is also referred to as Blende or Zinc Blende, and is the major ore of zinc. Occasionally it will be transparent with a vitreous luster. Sphalerite has a dispersion that exceeds that of all of the popular gems and is three times higher than the dispersion of diamond. When iron content is high it is an opaque black variety, marmatite. In the crystal structure, zinc and sulfur atoms are tetrahedrally coordinated. Because sphalerite often forms in veins and cavities, excellent crystals are relatively common. 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]. Similarly, ‘blende’ is from the German for ‘blind’ or ‘deceiving’. The chief uses for metallic zinc are in galvanizing iron, making brass, (an alloy of copper and zinc), in electric batteries, and . When Cd, In, Ga, Ge and Ta are present, they are recovered from sphalerite as well. It consists largely of zinc sulfide in crystalline form but almost always contains variable iron. Some specimens have a red iridescence within the gray-black crystals; these are called "ruby sphalerite". Often mined for minor amounts of indium, cadmium, germanium, or gallium as profitable byproducts. Faceted stones for collectors. Add to Cart. It is transparent to translucent and varies greatly in color, iron-free specimens being pale yellow and those with iron being brown, red, black, or green. The pale yellow and red varieties have very little iron and are translucent.

Crystals of suitable size and transparency have been fashioned into gemstones, usually featuring the brilliant cut to best display sphalerite's high dispersion of 0.156 (B-G interval), over three times that of diamond. It is a popular stone with collectors because it has a dispersion that is three times higher than the dispersion of diamond. In stock. This crystal is a zinc ore that usually consists of iron. The darker, more opaque varieties contain more iron. 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. This name is in response to the many different appearances of sphalerite and because it can be challenging to identify in hand specimens. 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.
