RAPAPORT... Sotheby’s will hold an April sale of Magnificent Jewels and a single owner auction, "Always in Style: 150 Years of Artistic Jewels," in New York on April 20, 2010. A majority of the white diamonds that will be featured there are the highly sought, wearable sizes weighing 10 carats and less. One such example is a platinum and diamond ring set with a 9.25-carat, D, internally flawless, type IIa stone, graded triple-EX and assigned a presale estimate of $1 million to $1.5 million.
A highlight of the colored diamonds on offer is provided by a rare fancy intense, pinkish-orange diamond ring set with a 7.67-carat, type IIa, cut-cornered rectangular modified, brilliant-cut stone that is the largest flawless or internally flawless diamond of this hue to be graded by the GIA to date.

Another superb example is a magnificent, fancy vivid yellow diamond necklace (pictured), which features 42 GIA-certified, fancy vivid yellow diamonds weighing a total of 100.17 carats and set in a graduated riviere style. This necklace boasts a presale estimate of $2 million to $3 million and Sotheby's has contended that it will be the first of its kind — set entirely with fancy vivid yellow diamonds — to appear in auction.
An 8.66-carat ruby and diamond ring, which Sotheby's described as "one of the finest ‘pigeon blood red’ rubies to be offered on the market," carries a presale estimate of $1 million to $1.5 million. This historical stone is the property of the Gardner family and was formerly included in the collection of Isabella Stewart Gardner, the philanthropist and visionary patron of the arts whose art collection is housed in the Boston museum that bears her name.
"Gardner loved jewelry and was depicted by painters John Singer Sargent and Anders Zorn theatrically wearing her rubies on ropes of pearls. According to a letter found in the Gardner family archives, the ruby on offer was acquired from a rajah who sent the stone to Mrs. Gardner in Paris, as she was known to be seeking a ruby in memory of her brother, Charles Stewart," Sotheby's stated.
