Comment: My favorite cut for light colored gems. Like the others from this Sri Lankan mine (3.61, 1.49) the hue is that of a sky at different times of a cold northern day. An interesting observation can be made in the side-shot under 'more images'. There you look right into the ideal color axis of the gem, a completely different blue, closer to cornflower than sky-blue. If the lapidary had cut this gem with the face-up in this direction we would have a very different, warmer blue. Probably the rough would not have yielded a full gem, hence the cutter decided to go for bigger and sparkly, rather than small and deeper colored. Since this is a precision-cut, we can assume no mistake was made. See the 36fold magnification of inclusions from space, beautiful but lens-only. With near 6x6mm big enough for a ladies ring, solitary or with halo. 3xNo-quality standard fulfilled. IGI report with 'unheated Ceylon'. Free global shipping. Lots of fire, always blue, pays for rainforest protection (more important than ever), animal rights, and all original paperwork to assure future value.
