Sphalerite streak
Diagnostic Properties. High specific gravity. Its silvery color on freshly broken surfaces can be used to separate arsenopyrite from pyrite and marcasite. Crystals are sometimes striated or twinned. A slight odor of garlic might be noticed when arsenopyrite is crushed, broken or scraped across a streak plate.Wurtzite Sphalerite Group. Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear to white crystals (known as Cleiophane ). Yellow to orange sphalerite is often called "golden sphalerite." Red shades of sphalerite are known as Ruby Blende or Ruby Jack.

The three are called polymorphs (meaning many shapes) because although they have the same chemistry, (Zn, Fe)S or zinc iron sulfide, they have different structures and therefore different shapes. Sphalerite is by far the more common mineral of the three. ….

Generally, the streak color is different from the color observed in hand sample, and it can be much more diagnostic for identification purposes.
