Attractive specimen of lustrous, olive-green Sphalerite var. Cleiophane crystals up to 8mm, growing on thin Quartz crusts from the famous Madan ore field, Bulgaria. The Cleiophanes popup nicely. They are transparent and gem with nice rich color, which contrast very well. They have glassy faces that beautifully reflect the light. Small Galena crystals are seen too. In excellent condition – some small contacts. On acrylic base.

Exquisite gem Sphalerite!
