Small Cabinet, 7.5 x 6.0 x 5.5 cm
Mursinsk, North of Sverdlovsk, Ural Mountains, Russia

Blue topaz crystals from the Urals have been treasured for the last 200 years. Although the color of this matrix topaz specimen is nearly colorless (pale), it is still a significant piece for this association. A glassy and gemmy, 4 cm tall topaz crystal is nestled among tan colored spherical masses of feldspar and included and matte lustered smoky quartz crystals, to 3.2 cm in length. These topaz crystals can be 'blued up' by exposure to radiation. ex Silby Collection, and also with a label on the back from the Richard Kosnar collection. An old classic!
