ED86D6: The specimen is nice but it also comes from an unusual locality, even though one initially assumes that it is from Los Lamentos. This comes from the dispersion of the Bally Museum collection so has a label with it that we will send to the purchaser. In a few crystals there is minor damage, but it is not very significant and none of the major crystals has any damage.
