The blue diamond led the sale, followed by two items which both sold for above their high estimates. An octagonal step-cut 21.38-carat sapphire in a platinum ring set with tapered baguette-cut diamonds sold for $4.5m.
And an 8.92-carats fancy vivid yellow-orange pear modified brilliant-cut diamond, in a platinum and gold ring, with pear brilliant-cut diamonds of 1.12 and 1.11 ct, sold for $4m.
