A remarkable and LARGE, 40-gram crystal of this rare complex iron-cobalt sulfide. It is complete all around except for a contact on the bottom and one small contact or old damage in a 7 x 5 mm edge on one face. It is geometric and very 3-dimensional, displayable from 3 sides thus. Most crystals I have seen are thumbnails, 1 cm or so, maybe 5-10 grams max. A 40-gram whopper like this, I have not seen for sale. It turned up at Munich with a collection dispersal, and the collector's notes said he had exchanged it from the Phillipstad Museum in Sweden (over 50 years ago). The photos just do not convey how good this is. It looks like a pyrite crystal with carrollite color. Its really bright, really big, and really important. For the price, you get a killer sulfide of super rarity in this quality!
