Sphalerite is one of the few minerals that can range from gemmy transparent crystals to dark, metallic -black crystals. An interesting variety of Sphalerite is known as Schalenblende. Schalenblende is banded variety associated with Wurtzite and often also Pyrite and Galena that forms strange concentric shapes.Mar 3, 2005 · Sphalerite forms beautiful and often complex crystals. Their color can range from (rare) colorless through shades of green, yellow, orange, red, brown, and black - all determined by the amount of iron impurities. (Pure synthetic zinc sulfide is colorless.) Faceted sphalerite is gorgeous - it has twice the dispersion (fire) of diamond!

collin secton Sphalerite, zinc sulfide (ZnS), the chief ore mineral of zinc. It is found associated with galena in most important lead-zinc deposits. The name sphalerite is derived from a Greek word meaning “treacherous,” an allusion to the ease with which the dark-coloured, opaque varieties are mistaken for.

Pure sphalerite samples can be distinguished from galena because they are harder (3.5 to 4) and have a lower specific gravity (3.9-4.1). The color of their streak provides an even simpler way to distinguish the two.Any unwanted rock and minerals, called waste rock and gangue, respectively, are usually discarded in tailings piles.

They allow scientists to build a historical record of the planet to learn what events occurred before people lived.1. Sulfur-The Original Brimstone.

Don’t forget that local streams are ideal places to search for those special ... Zinc sulfide (ZnS) is a unique compound that forms two types of crystalline structures. These two polymorphs are wurtzite and zincblende (also known as sphalerite). Wurtzite has a hexagonal structure, while zincblende is cubic. It is characterized by single bonds between each atom and maintenance of a 1:1 zinc to sulfur ratio.
