Sotheby’s To Auction 133-Carat Yellow Diamond
The stone headlining the upcoming sale could fetch up to $5 million.

The 133.03-carat fancy vivid yellow diamond is estimated to sell for $4 million to $5 million.
Other diamond pieces making an appearance include a necklace with 95 pear-shaped diamonds.
Weighing more than 28 carats each, two pear-shaped diamonds on the ends of the necklace hang suspended from two rows of similarly cut diamonds totaling 120.20 carats.
A 35-carat cushion-cut diamond and a 7-carat fancy intense orangy pink diamond, as well several diamond pieces from Harry Winston, are also being offered.
In addition to the diamond offerings, the auction will also feature pieces from the collections of Hollywood stars, including two belonging to Frank Sinatra’s wife, “Lady Blue Eyes,” Barbara Sinatra.
The couple spent more than two decades together.
Barbara received several jewelry gifts from her lover over the years, including the two pieces featured in the upcoming sale—a Bulgari emerald, diamond and cultured pearl choker and a 16.19-carat diamond ring.
Sotheby’s will also offer jewels from the collection of comedian Red Skelton and his wife, Lothian Toland Skelton.
Richard “Red” Skelton, one of the twentieth century’s most beloved performers, enjoyed a career that spanned various forms of media, and was notably furthered by the advent of television.
The advancement allowed him to share his skill with pantomime and physical impressions with a wider audience and led to the creation of “The Red Skelton Show” and later, “The Red Skelton Hour,” which ran from 1951 to 1971 and was one of the top ten rated shows for 17 of those years.
He built his jewelry collection over the course of his career, befriending Beverly Hills jeweler William Ruser and developing an eye for gemstones.
However, he did not want anything to interfere with his ability to engage with his audiences and to fully embody his characters, Sotheby’s said, so he kept his interest in jewels separate from his public persona.
The comic’s interest in jewelry may have come from his grandmother, who advised him that gemstones were a wise investment and could provide security for the future, according to Sotheby’s.
She gave him an emerald that he later had mounted in a ring, a piece that will be offered in the upcoming sale and is estimated to sell for $200,000 to $300,000.
Sotheby’s will also offer a Jean Schlumberger bracelet and Verdura ‘Sea Horse’ brooch from the collection of Emmy-winning actor best known for playing Felix Unger in the television adaptation of Neil Simon’s “The Odd Couple,” Anthony Leonard Randall, and his wife Heather Randall.
In addition, the auction house will feature 21 pieces that once belonged to actress Mary Tyler Moore, the sales of which will benefit the Mary Tyler Moore Vision Initiative.
Other jewels from the houses of Van Cleef & Arpels, Cartier, Harry Winston, and David Webb will also be up for grabs.
