Fluorite & Quartz w/ Bertrandite (Robertson Coll.)

Item Description

Rich deep purple, moderately lustrous, sharp fluorite octahedrons, to 1.0 cm, are richly clustered in the large plate of jackstraw milky quartz crystals. This sculptural specimen of well-known distinctive fluorites is from the limited early 1990s finds at Akchatau. No more have been found and the mine is abandoned. Scattered about are tiny white bertrandite plates, a typical accessory from the find. Ex Kay Robertson Collection # 12336 and acquired in the 1990s. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record). Specimens are highly prized and are seldom on the market today.
