Hydrozincite (fluorescent) with Calcite (Stoudt Coll.)

Item Description

Spherical aggregates of tiny, sparkly, acicular hydrozincite crystals richly covers the front of the sculptural, 3-dimensional gossan matrix along with a large cluster of glassy, translucent, iron oxide-tinted calcite rhombs (mostly on the back) on this showy and excellent combination specimen from the famous Mina Ojuela. Hydrozincite forms in the oxidation zones of zinc deposits as masses or crusts, especially those rich in sphalerite. Old-time material dating to the 1960s. Fluoresces a pretty white-blue. Ex Dave Stoudt Collection # 1188.
