Fantastic cluster of intergrown Dioptase crystals from Tantara Mine, Congo Kinshasa. They are strongly lustrous with dark emerald-green color and very sharp, perfectly terminated crystals. Some crystals are doubly terminated up to 19mm in length. The quality is superb; the crystals are gemmy with marvelous blue and green nuances. Some very small snow white Quartzes add a nice contrast. On the back side are seen cream colored Calcites. In excellent condition – some outside edges contacts. On acrylic base.

Sumptuous Dioptase!
