Comment: A strong blue sheen on top of a 100% transparent body is the Shangri-La of all moonstones. No inclusions and no hint of color except that blue sheen, floating seemingly detached in space, makes for one of the most fascinating magical effects in the gem-world, next to stars, cat's eyes, iridescence, play-of-color, rainbow-colored dispersion, to name a few.... though in this august line-up, even finest moonstones are the least expensive variety. BTW, no blue sky or blue day-light has been used to strengthen the blue sheen; it is really that blue in any light-setting. If memory serves right, this gem has a brother/sister to make a pair waiting for publication (let us know if you seek a pair). In ring or pendant, this moonstone will make for a great show. Prepare for many 'show-me-again' requests.
