“A beautiful 7mm green sphere of kidwellite, the rare phosphate from Arkansas. This is a REALLY good kidwellite! Rarely do you get them so nice and isolated, instead of just as a crust on matrix. This is an old specimen, obtained fro Al Kidwell in all likelihood back when Marty lived in Texas as well. 5.4 x 3 x 2.5 cm
