This piece features the face of a dioptase seam, covered with beautiful dioptase crystals. The dioptase crystals are sharp and glassy, with unusually good translucence. In excellent condition, tiny missing crystals in a couple of spots, and contacting at the front bottom where this was attached to the surrounding rock. The specimen has been prepared using a saw to reduce excess rock, at the bottom and lower part of the backside – as a result it stands and displays perfectly as photographed. These crystals are as lustrous as dioptase gets, and they really glow under the lights with the internal play of light.
