A sweet miniature with exceptional sharp free standing crystals. The crystals are up to about 3 CM tall most of which is aerial. No damage by naked eye on the display face which is incredible for such a delicate mineral. 10 x magnification finds some minor edge chips that are just not noticeable. the back of the matrix has been sawn in order to collect this without damage. Bou Azzer is unquestionably the worlds best locale for many Cobalt minerals and especially for Erythrite. This is far above average.
