Kara-Oba Tungsten deposit, Betpakdala Deseert, (Qaragandy Oblysy; Karaganda Oblast'), Kazakhstan

    Among the many things that the Kara-Oba Tungsten deposit has furnished over the last 20 years or so has been some very nice Smoky Quartz plates in association with a variety of other minerals. Here we have a matrix plate of massive Smoky Quartz that has sprouted a veritable forest of Smoky Quartz crystals up to, approximately 2 inches (5.0 cm) in height. The neat thing about the specimen is the selective deposition of some rhombohedral carbonate crystals, presumably Siderite or Ankerite, on one side and one side only, of the Smoky Quartz crystals. The tan color of the "Siderite" is a very nice complement to the deep brown of the glistening Quartz. The condition is pristine.
    Overall measurements: 7.5 x 5.5 x 3.0 inches (19.1 x 14.0 x 7.6 cm).

    Provenance: Collector's Edge [Hoppel # D0138]

    It would indeed have been much simpler to work with a local auction house, and we had local options. But we never once regretted going with Heritage.
