Sphalerite, also known as Blende or Zinc Blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colours ranging from pale yellow (known as Cleiophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite).
