Kara-Oba W deposit, Betpakdala Desert (Bet-Pak-Dal Desert), Qaraghandy Oblysy (Karaganda Oblast'), Kazakhstan Octahedral Fluorite with Pyrite and Sphalerite from Kara-Oba, Betpakdala The crystal is forming a complex growth in two different phases. In the first one the major octahedron formed and then on the octahedron vertices, smaller Fluorite crystals with dodecahedrons grew. Sphalerite and cubes of Pyrite form a perfect base to the sample. The ... |

Kara-Oba W deposit, Betpakdala Desert (Bet-Pak-Dal Desert), Qaraghandy Oblysy (Karaganda Oblast'), Kazakhstan 12.4 x 6.4 x 5.1 cm. An extremely unusual combo specimen from Kazakhstan, of good size! This fascinating piece is a free-standing intergrowth of purple and gray fluorite octahedrons with quartz crystals, both conventional in form and tabular. Pyrite here and there adds a sparkly golden accent that does not come through very well in the pics. ... |
