Altyn-Tyube (Altyn-Tube) deposit, Kirghiz Steppes (Asiatic Steppes), Qaraghandy Oblysy (Karaganda Oblast'), Kazakhstan WOW! This is just an AMAZING dioptase specimen, especially for Russia (the type locality - no, it is NOT Tsumeb!). It features a HUGE, FAT crystal 1.7 cm from top to bottom and 1 cm thick, that crowns a cluster of smaller crystals of equally fine luster and color. This is just a standout specimen for what it is. 4.1 x 3.2 x 2.4 cm |
