Comment: In ten years we have seen owned only one such sapphire (also an emerald shape if I remember correctly). Clearly proof of how much sapphire has to offer. Clean cut blue to yellow color zone right in the center and vertical to the stone - great stuff! Such a gem is cut for color not for brilliancy (obviously). It does not get more unique in the world of colored gems. Inclusions visible only under the lens (and 36 magnified image). See side image: A small crystal (tourmaline or zircon?). Magic! You will not find such a wonder in treated sapphire.
