<dd>This central crystal is 4.6 cm tall. I have seldom seen or heard of such a giant dioptase crystal from any locale. You just keep looking to see that it surely must be a composite crystal but, it is not. It is a straight, 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.
