Comment: The certificate of this Montana was eaten by the dogs or elsewhere mislaid (in any case never my fault). We will remake it if you wish, or give you a $200 discount if you don't need it. The gemologist can tell you from the visible silk in the photo that the gem was not heated. If you look close you can even see the hexagonal crystal structure. The color is a classic Montana mix of cold green-blue. Though silky it shoes a remarkably high brilliancy. Value deal.
