Cosalite, Fluorite
Kara-Oba W deposit, Betpakdala Desert (Bet-Pak-Dal Desert), Qaraghandy Oblysy (Karaganda Oblast'), Kazakhstan
Miniature, 4.5 x 4.0 x 2.7 cm
A RARE and showy combination specimen from Kara-Oba, Kazakhstan and the Eric Asselborn Collection. Metalllic-bright cosalite needles are aesthetically crossed and included within a water-clear, sea-green fluorite cube with purple zoning. The cosalite needles are revealed through a thin, secondary fluorite overgrowth layer. Cosalite is an uncommon lead bismuth sulfide. The scattering of quartz crystals are a nice accent to this mounded, 3-dimensional piece.
