A rock containing three crystals of pyrite (FeS 2).The crystal structure of pyrite is primitive cubic, and this is reflected in the cubic symmetry of its natural crystal facets. A network model of a primitive cubic system The primitive and cubic close-packed (also known as face-centered cubic) unit cells. In crystallography, the cubic (or isometric) crystal system is a …Sphalerite pseudomorphs may also have the crystal structure of similar minerals like calcite or galena. You can identify sphalerite by its six-sided perfect cleavage, luster, and streak. "Streak" refers to the color of a mineral's powder after scraping it across a streak plate like unglazed porcelain.Check out our sphalerite crystals selection for the very best in unique or custom, handmade pieces from our home & living shops.

It’s known for its adamantine luster and can range in color from yellow to brownish-black, green, or red, depending on the amount of iron present. A common specimen of sphalerite contains dark crystals that shimmer when viewed under direct light.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.
