Comment: Near colorless sapphire from icy Montana. See the faintest blue tint in the side images. Adamantine gemstone and yet not just a mundane every-body-has-one diamond. As with all sapphires Montanas get heated routinely; only the very best are good enough to be cut and polished just as they are found without any artificial enhancements. Pure and beautiful but tough. Under the lens it shows strange liquid swirls.
