103.8-ct. Stone Fails to Sell at Sotheby's, Smaller Diamonds Sell Well
Though a largely publicized diamond—a 103.83 ct. flawless D color stone—disappointed Sotheby’s by not finding a buyer at the magnificent jewelry auction in November, Sotheby’s did register several important diamond sales—primarily fancy colors.
The much-hyped stone, the largest D color internally flawless stone, was estimated to fetch up to $10 million, but went unsold.
Top sales, meanwhile, were:
A 5.07 ct. fancy intense pink diamond sold for $1.77 million, or $349,155 per carat.
A pair of fancy vivid blue diamond earrings, weighing 4.06 ct. and featuring 5.39 ct. of white diamond accents fetched $1,555,650.
A 13.99 ct. D-color, internally flawless diamond ring, which sold for $757,260, or $54,128 per carat
A 10.57 fancy vivid yellow stone sold for $718,630, or $67,987 per carat.
The auction season, however, is far from over, with Sotheby's holding a high-profile jewelry sale December 12 in New York. Among the diamond pieces on the block this time around are several rare fancy colored diamonds: a fancy colored diamond pendant, expected to fetch up to $1.2 million, features a fancy green-blue briolette weighing 8.81 cts and three other blue-ish diamonds as accents; a 13.09 ct. fancy pink-purple stone is also for sale, featuring a GIA report determining that the predominant color is purple (price estimate available only on request), and a fancy vivid blue 5 ct. emerald cut diamond ring is expected to fetch $1.25 to $1.75 million.
