Exceptional specimen of gemmy Dioptase crystals from Tantara Mine, Congo - Kinshasa. It displays top quality piece for the mine with crystals up to 18mm growing in a cluster. The Dioptase crystals are strongly lustrous with dark emerald-green color and very sharp, perfectly terminated crystals. Some crystals are doubly terminated.  The quality is superior – very fresh and shiny. The crystals are gemmy with marvelous neon green nuances. Complete all over with beautiful display from all sides. Better in person. In excellent condition – some very small nicks and minor contacts.

Outstanding beauty!
