Description

An aesthetic cluster of glauberite crystals that formed in the clays of this small salt lake north of Adelaide.

It is in unusually good condition as the surface of these tend to alter to white powdery gypsum. This piece was collected over 10 years ago and shows only minor alteration and actually tends to enhance the specimen. Great condition with only minor chipping.
