Beryl & Schorl Tourmaline, David Ost Farm, Erongo, Namibia

Colour-zoned beryl crystals with nicely contrasting black schorl tourmaline radiating sprays. Most of the beryls begin as a white or colourless beryl (technically goshenite) but turn a nice shade of green near their sharp terminations. The slightly etched beryls range from tiny needles to the 4.5 cm long main crystal. Ex Mike Menzies collection. From David Ost Farm, Erongo Mountains, Erongo Region, Namibia. Dimensions: 2 x 4.5 cm
