Sotheby's Geneva to Auction 52.82-Ct. Diamond


Sotheby’s Geneva will hold its spring 2010 sale of Magnificent Jewels and Noble Jewels at the Beau-Rivage Hotel on May 11, 2010. At the heart of this sale will be an emerald-cut diamond weighing 52.82 carats, as well as a pear-shaped, fancy vivid blue diamond weighing 5.02 carats, both of which are set as rings.   

The extremely rare 52.82-carat diamond was determined to be a type IIa, D, flawless with excellent polish and symmetry by the Gemological Institute of America (GIA). Sotheby's estimated that the ring would  fetch over $7 million. 

The 5.02-carat blue diamond is set in the form of a toi et moi ring (pictured), which was designed and created by Alexandre Reza. The blue stone is mounted alongside an exceptional 5.42-carat diamond with the same shape. Its estimated sale price ranges from $4 million to $7 million.
