Shortite
Shortite is named after M.N. Short, Professor of Mineralogy, University of Arizona, Tucson, USA.
Shortite forms characteristic transparent colourless, light yellow, yellow, light green wedge-shaped crystals. The material slowly decomposes in water.
Shortite is a very rare gem. Faceted stones are scarce.
