This piece features GEMMY, sharp, brilliantly lustrous blue topaz crystals on matrix and only a handful of world localities have EVER produced such. Note the quality an dcomplexity of that large crystal and its bevelled terminations, please...this is an outstanding matrix blue topaz from ANY locality, standing on its own merit! Again, this is ERONGO and not from the more common and assumed best Namib topaz locality of Spitzkopje! This took me by surprise. I had not seen such fine Erongo topaz before! And, its much MUCH better in person. The rich, pastel blue color it has, does not show well in photos here.
