Polished as an oval cabochon with a high dome, this sapphire of classic Sri Lankan cornflower blue, possesses a very unusual form of asterism: when the stone is illuminated with a single point light source, two superimposed six-rayed stars appear. The rays of one star are almost parallel to, and just to the side of, the other.
Weighing approximately 38.56 carats and measuring 16.5 x 15.0 x 12.0mm
