M.S. Rau Antiques in New Orleans will present one of the world’s rarest blue diamonds, valued at $9.85 million and weighing 10.6 carats, at a VIP collector’s evening on Wednesday, October 9, 2013 at their booth at the Antiques and Art show in New York, sponsored by Avenue Maazine and taking place at The Park Avenue Armory at 643 Park Avenue (66th and 67th Streets). If you can’t get to the Smithsonian Museum to see some of the world’s rarest diamonds, then stop by M.S. Rau Antiques’ booth to view this exquisite rare and priceless blue radiant-cut diamond, which is set in platinum and surrounded by pink diamonds.The Royal Blue Diamond is certified by the GIA (Gemological Institute of America) as VVS1, one of the highest ratings ever issued for a natural fancy colored diamond. Blue diamonds are rare and it’s not unusual for their prices to be 10 times more than a near-flawless white diamond. They are blue because of the mineral boron. For more information, vist M.S.
