I saved this jewel-like thumbnail from the inventory of a gemstone dealer measured out as cutting rough at 15.73 carats. It is one of the sharpest hexagonal bastnaesite crystals I have ever seen, with incredible gemminess and a deep, robust color. These are among the best of species from Zagi Mountain. Usually they are larger and fatter, seldom so aesthetic. The feature that really makes this piece next level is the slight beveled edge around the perimeter with extra faces and extra reflections. It is a world class thumbnail of the species, no doubt. Joe Budd photos.
