Comment: This is not only a gemmological miracle (faint blue cobalt spinel) but also a stunning beauty. Proudly presented. Guebelin certified no-heat and cobalt. Plainly spoken: looks like fancy blue diamond only better. Cannot be cheap (sorry). Defies the camera, and the mind.  Excellent cutting. No visible inclusions. Blasting with brilliancy. See blue in side image. See lustre in handshot. Haven't had so much fun in weeks! What a gemstone! (If it were not repetitive I would make another bet: you can't find a second one.)
