For the species, a cobalt-containing sulfide, this pair of penetrating crystals are absolutely choice. It is a floater and is complete all around save for the most minor of wear on a few edges. For lustre and 3-dimensional form, this is top quality....Rarely do you see Glaucodots this sharp and well-defined, and the bright metallic luster caps it off. Like so many of her rarities, this is competition-quality for sure. 1.9 x 1.8 x 1.6 cm
