Lake Gilles Gypsum Deposit, Corunna Station, Iron Knob, Eyre Peninsula, South Australia, Australia

Group of twinned "hourglass" and "fishtail" gypsum crystals. Specimen with very good transparency, colorless and doubly terminated. It comes from the famous Lake Gilles in South Australia. The crystal is floating and its transparency allows us to see the inclusions of arrow-shaped clay particles. Lake Gilles produces some of the most unusual gypsum crystal shapes in the world.
