This collection of minerals is uncommon in such quality and we have become accustomed to just the dioptase from Kaokoveld, however, this is much more rare. Barite is an unusual mineral associated with dioptase from this locality and the two minerals provide a pleasing contrast of colors, plus such a specimen is the No. 1 spot for the association. The barite itself is 2.2 cm and surprisingly complete without damage. Ex. Bolyard collection
