Marvelous twinned Sphalerite decorated by brown-orange Calcite balls. Displays black Sphalerites crystals with very strong luster, complex structure and superb twinning. Sphalerite forms very aesthetic finish at the top. The Calcite balls are well isolated and contrast strongly. Small Quartz crystals are seen too. Complete all over 360 degree. In excellent condition – some small nicks. On acrylic base.

Beautiful!
