Wardite
Wardite is named after H.A. Ward, Professor of Natural Sciences, University of Rochester, New York, USA, mineral collector and dealer; founder of Ward's Natural Science Establishment.
Wardite forms transparent to translucent colourless to white, pale green or blue-green typically striated dipyramidal pseudo-octahedral crystals.
Wardite is cut into cabochons and rare crystals can make attractive gems.
