Chalcoalumite and Hydrohetaerolite Hardscribble Mine, Magdalena, Socorro County, New Mexico. Material collected in 2004 and analyzed by Dr. Vergil Leuth at the New Mexico School of Mines. I purchased this as reference piece. This one measures 8 x 5.5 x .8 cm and is dominated by the green colored chalcoalumite and minor blue colored hydrohetaerolite. Mostly botryoidal forms and some very tiny crystals. $60
