<dd>This central crystal is 4.6 cm tall! I have seldom seen or heard of such a giant dioptase crystal from ANY locale. The thing is crazy big - you just keep looking to see that it surely must be a composite crystal but, it is not. It is a straight, honest to god, single large crystal. The big one is flanked by smaller crystals (mostly complete, though a few have edge contacting), all with electric green color, good lustre, and a glowing translucency that will make this pocket famous , I predict. It is hard to photograph dioptase, and I assure you these are quite better in person, this in particular. Mounted on a base, and stood in a case, it makes a very imposing full miniature. If it were from Tsumeb, you could add a zero to the price, too; but Kaokoveld is contemporary and mined more cheaply, so even great specimens do not cost as much as they should based on historical precedent for this species. Price aside though, this IS a great piece, worthy of any major collection.</dd></dl></dd></dl>
