Gypsum (excellent twinned style - old!) ex Kidwell Coll.

Item Description

A superb, dramatically sculptural and pristine two-sided stacked cluster of lustrous sand-included fishtail-twinned gypsum crystals from the well-known Great Salt Plains at Jet, Oklahoma. Twinned crystals of this style and quality are rare from here and this an outstanding example. From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974. Al acquired this fantastic old-timer in 1958! While common en masse, specimens like this are simply oldtimers we never see today
