The chemical symbol for the elemental zinc is indicated by Zn. Native Zinc is actually classified under the Native Elements mineral class. There are so many applications for the metal zinc. Native Zinc is actually a rare mineral. Although Native Zinc is found in several locations, it is never found in great abundance. The Native Zinc could be misidentified as an ore of zinc because it has been known, also in optical mineralogy, that an ore should be less valuable that its constituent metal. Moreover, an ore should be common enough and exploited enough to be profitable enough to mine. The first specimen of Native Zinc came from New Brunswick, Victoria, Australia in the year 1855. Native Zinc is usually found as indistinct grains in igneous rocks with origination from a reducing environment.

             Native Zinc is most commonly found white to bright blue gray in color which could appear more fascinating when viewed with the aid of petrographic polarizing light microscope used in the field of optical mineralogy. Native Zinc is most commonly found exhibiting nice and interesting microscope appearance when viewed with the aid of polarized light microscope used in the field of optical mineralogy. It is found showing metallic luster in reflected light of polarizing microscopes for mineralogists. Most specimens of Native Zinc are found opaque in appearance. Native Zinc is most commonly found crystallizing in the hexagonal system of crystal formation. In optical mineralogy, the hexagonal system of crystallization comprises crystals having four axes. Three of which are positioned in a single plane with equal length and are symmetrically spaced. The fourth axis is found to be perpendicular to the other three axes. The crystal habit of Native Zinc as described in the field of optical mineralogy usually include volcanic exhalations, granular that is often microscopic and also lab grown specimens. Native Zinc is also usually found showing perfect basal cleavage in one direction that can be seen more clearly exhibited under polarized microscope used in optical mineralogy. The hardness measure of Native Zinc when it is evaluated using the Mohs scale method is usually found 2. The specific gravity measure of Native Zinc is usually found ranging from 6.9 to 7.2, which is heavy even for a metallic mineral.              Native Zinc is usually found brittle at room temperatures. It is however not malleable or ductile unless heated up to 100 degrees Celsius. Native Zinc is usually found leaving a light gray streak when rubbed on a white porcelain streak plate. Native Zinc is usually found associated with other interesting minerals including native copper, native gold, native aluminum and many other rare native metals. The best field indicators of Native Zinc usually include density, color, hardess, locality and brittleness. Native Zinc notably occurs at several localities including the type of locality of Mina Dulcinea de Llampos, Copiapo, Chile and several other countries such as Canada, Australia, Austria and some areas in Russia.
