A rare Fancy Intense Pinkish Orange Diamond Ring (est. $2.5/3.5 million) will headline Sotheby’s upcoming jewelry sale next month in New York.

Always in Style: 150 Years of Artistic Jewels and Magnificent Jewels, is actually comprised of three separate sessions. The first session is simply an extensive survey of period and signed jewels from the 19th century up until modern times, which represent the principal design themes of those time periods.

Magnificent Jewels, the second session, features stunning diamond and colored stone jewels from some of the most prestigious collections including Patricia Kludge, Ann Getty, and the Nancy M. Daly estate. Jewels that were former members of the Marlene Dietrich and Isabella Stewart Gardner collections will be offered as well.

The highlight of the second session is the rare Fancy Intense Pinkish Orange Diamond Ring that is 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 color graded by the GIA. Coming in right behind it is A Platinum and Diamond Ring (est. $2/3million) that is set with a 9.25-carat round diamond of D color, made from similar type IIa material. Coming from a distinguished collection, the ring carries a grade of triple-X, signifying its elegant cut, polish, and symmetry.

Rounding out the sale is the third session, Always in Style: 150 Years of Artistic Jewels, a single-owner collection of signed and decorative jewels created over the last two centuries, featuring Cartier, Daniel Brush, Marcus & Co., Giuliano, Boivin, T.B. Starr and Giorgio Facchini.

Notables from the April 20th sale will be on public exhibition at Sotheby’s Los Angeles office on March 26th and in Hong Kong from April 3-6. The presale exhibitions in New York will be held April 16 through April 20th.
