Blue Lace Agate (Ysterputs, Namibia)
Ysterputs, Karasberg region, Namibia. 140mm x 90mm x 4mm.
A really pretty nodule of "Blue Lace Agate" that has been sliced. Note this has not been polished. These "Nodules" date back to the early days of the mine - more recently there are mainly banded specimens that come out and no nodules. This material is in fact a form of Chalcedony but known as "Blue Lace Agate" the world over. (Packed shipping weight = 195gr)
