Product Description
An extraordinary 49.51 carat natural gray star sapphire, certified by the Gemological Institute of America (GIA) Gemological Institute of America, exhibiting the captivating optical phenomenon known as asterism.
This remarkable gemstone is cut as an oval double cabochon, the ideal shape and finish to reveal the star effect that glides gracefully across the surface when exposed to a focused light source. Its soft gray body color and luminous silken structure create a mysterious and elegant appearance.
