Iridescent Goethite (ex Al Kidwell Collection)

Item Description

A beautiful iridescent Goethite specimen from the Coon Creek Mine in Arkansas. The piece reminds me of similar specimens from Graves Mt. The silvery-grey color and botryoidal form of the Goethite is highlighted by the mixture of blue, purple, yellow and golden hues from the iridescent oxidation on the surface. The Goethite has formed in semi-parallel almost columnar bands, sitting atop massive Goethite matrix. These are RARE on the market, and date back 50+ years, so get your hands on this one because we don't know if we'll have another anytime soon. 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 ( https://www.mindat.org/photo-326405.html ).
