Sri Lanka, the island of exotic gems, has a colorful gem mining and trading history of at least 2500 years. It was once called Rathnadweepa, which means Gem Island in Sinhalese. Persian traders endearingly referred to the island as Serendip; presumably because the discovery of such magnificent treasures leads to happiness, good fortune and luck. Featuring a 4.88 carat AGL certified Ceylon sapphire that has indication of heat treatment. Heat treatment is permanent and a common practice with sapphires and rubies, which activates certain properties of the stone. It speeds up the aging process because age brings out the true color, without changing the composition or naturalness of the stone. Accented by shoulders of perfectly cut triangular shaped colorless diamonds. Crafted in platinum. Ring size 6 and can easily be resized to fit, if needed this would come complimentary with your purchase.
