Item Description

This is a rare specimen, the first I have personally seen, of material I could only find referenced in an Arizona Bureau of Mines report. Harold Urish selfcollected this in 1999 at the soccalled Gods Claim, here. It features unusual, acicular crystals of mimetite on a background of green mineralization which, according to that report as summarised on MINDAT, may be descloizite or bayldonite
