What is sphalerite gemstone?
Sphalerite gemstones: Sphalerite is occasionally cut as a faceted stone. It is a popular stone with collectors because it has a dispersion that is three times higher than the dispersion of diamond. The stones occur in a spectrum of colors ranging from yellowish green, to yellow, to orange, to red. To exhibit the excellent dispersion the stones must have a very high clarity. 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.
