Ex. E. Morales from J. Minette, Washinton Mineral Symposium, 1982

A cluster of fairly large, well formed Colemanite crystals which range in color from white to clear. The terminations of the crystals are sharp and stiletto like. The crystals have a high, glassy luster. Purchased from the manager of the mines who also assembled, what was considered by many, the world's best borate collection.

Condition: Very Good

Flaws: There are a few small terminations at one end of the specimen that are not complete.
