Sphalerite (fine crystals) with Dolomite (ex Al Kidwell Collection)

Item Description

A fine quality Sphalerite from the famous area around the Picher Field in Oklahoma. This small cabinet specimen hosts several rather sharp, semi-lustrous, well-formed, nearly black, modified crystals of Sphalerite measuring up to 1.9 cm across with minor rhombic Dolomite on a thin layer of matrix. Good quality and beautiful from the crystallographic standpoint. Great old classic material from the tri-state region. It's hard to find such well-formed isolated Sphalerites on matrix like this from Picher. 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.
