SPHALERITE FLUORITE CLUSTER
Large matrix of lustrous red gemmy Sphalerite Fluorite Cluster combo. This is a quality piece of solid sphalerite that would grace any collection. A great metal specimen from a well-known locale. My pics don’t do it justice.
Elmwood Mine, Carthage, Tennessee.

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 Cleophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite).
