Untreated Burma Sapphire Ring, 35.07 Carats, $2,450,000. © M.S.Rau Antiques.

The vibrant color of this untreated Burma sapphire is perfectly presented in this classic platinum and 18k yellow gold ring. Boasting 35.07 carats, the sapphire exhibits a velvety royal blue hue, the color most desired in Burma sapphires. The brilliant cut of the gem perfectly displays its color, and two diamonds totaling 1.54 carats further enhance this natural stone’s radiance. The sapphire is certified by C. Dunaigre and the Gemological Institute of America (GIA) to be natural with absolutely no heat treatment, making this truly one of nature’s most magnificent treasures.

For centuries, Burma has been associated with the world's bluest sapphires, and its history is rich with intrigue. While Burma was a bountiful source of both sapphires and rubies for more than 1,000 years, the best stones were never allowed to leave the kingdom. Until the middle of the 19th century, the Burmese king commanded that any and all gemstones weighing more than 5.00 carats would become the possession of the kingdom of Burma. Miners, anxious to sell their gems, broke many magnificent sapphires into pieces smaller than 5.00 carats so as to bypass the king’s law. Sapphires such as this, weighing over 5.00 carats, are exceptionally rare and precious. The opportunity to acquire a Burma stone of such substantial size and perfect color, is indeed, a rarity.
