This fantastic 3.70 cts Antique Cushion Cut Sapphire was set into a Georgian inspired three stone ring. We flanked it by a pair of repurposed round faceted diamonds. 

The color is a rich, deep velvety blue, eye clean stone and was removed from an Edwardian ring that was too damaged to restore. We recently sent it to GIA Laboratory to test it and it came back UNHEATED, which is so RARE!
