Description

You are bidding on a world class sample of these two extremely rare minerals from the type locality. There are numerous pink bladed clusters of coskrenite-Ce among the hairs of apjohnite. In two spots (red arrows) are custers of tiny, square prismatic colorless crystals of extremely rare levinsonite-Y. You can see them well by their vitreous luster compared to the other species. Only about 30 specimens of this mineral have been noted. My last specimen!
