SPHALERITE QUARTZ CRYSTALS
A very cool Sphalerite Quartz Crystals Cluster. This cluster looks a little bit rustic from a distance, the closer you get the better it looks! A mainly quartz matrix with many tiny to small perfect Quartz crystals. Many of the quartz crystals have tiny Sphalerite crystals on and inside them. That alone makes this piece spectacular. Add the larger Sphalerite bordering on Cleiophane rose like formations and I should be keeping this one! Put a smile on your dial with this great piece. Your collection will thank you for it.

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).
Quartz is the most common mineral found on the surface of the Earth. A significant component of many igneous, metamorphic and sedimentary rocks.
