Feldspar, Hyaline Opal, Schorl & Quartz (Erongo, Namibia)
Erongo, Namibia. 110mm x 50mm x 40mm.
In it's own right this is quite a attractive specimen, pop it under the SW UV light and it is really something to enjoy. These are great when one can see the fluorescence from the hyaline as vividly as you will see with a specimen like this. Packed shipping weight +/- 300gr.
