Description

Here is an excellent specimen of ideally crystallized colemanite crystals on matrix. The colemanite crystals show a high transparency, the typically spear-shaped habitus and reach to a length of 2.5 centimetres. This is a very aesthetic collection specimen of high quality.

The specimen comes from the collection of Dr. G. Jung, who received it from B. Rowley (Sta. Ana) in 1971.
