Calcite (classic locale) Kidwell Coll.

Item Description

Intergrown lustrous, translucent to transparent calcite scalenohedrons from a sculptural and aesthetic large specimen from the Picher Field, Oklahoma portion of the historic Tri-State District. The crystals reach 7.5 cm and some are doubly terminated, adding character. Scattered flecks of included marcasite are a nice accent. A very showy pristine 360-degree piece with only very modest basal periphery wear. Ex Al Kidwell Collection and acquired from well-known Tri-State mineral dealer, Chink Enders, in 1964 before the mines closed. 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. See the 2017 Mineralogical Record Tri-State District! Special Issue in Vol. 48, No. 2. A fine large example of the calcite varietal from the District.
