  • This is an interesting piece! The larger crystals appear to be epimorphs of safflorite after skutterudite crystals. Under the epimorphs there is nickeline, some of which is in small crystals. The top of the epimorphs are sprinkled or covered with tiny, sparkly skutterudite crystals. Displays very well, just as in the photos. Excellent!

  • A very nice specimen of botryoidal safflorite that has patches of small silvery skutterudite crystals here and there on and between the safflorite botryoids. The "botryoids are actually radiating groups of silvery safflorite crystals with the outsides the terminations of pointy crystals. The skutterudite crystals are small very silvery cubes modified by octahedral faces. Very nice specimen of a mineral we don't often see in the world!
