Item Description
A classic example of Neptunite from the famous Dallas Gem Mine. While this locality is best known for its supreme Benitoite crystals, the Neptunites are also the best in the world for what they are. This piece is a wonderful group of sharp, lustrous, rich reddish-black colored Neptunite crystals with a beautiful accenting balls of grey-blue colored "Crossite" (a now discredited species, defined as an intermediary between Riebeckite Glaucophane). I love how the Neptunites are slight curved, giving the piece real character and visual appeal. 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 ).
