Costume Jewelry Ring Turns Out to be a 26.27 Carat Diamond

"Even if it was just a small 1-carat diamond it would be amazing, but the fact that it's 26 carats, that's larger than most would see in their lifetime let alone own dream of owning. To have one this big and truly pure is astounding,"  -Jessica Wyndham, head of Sotheby's London jewelry department; photo courtesy of Sotheby's Auction House

One lucky lady bought more than a fun cocktail ring for about 10 pounds (about $15) 30 years ago. This piece of "costume jewelry" turned out to be a 26.27 carat white diamond. The owner has been wearing the ring since the '80s and only recently found out from a local jeweler it could be of significant value. On Monday she met with with Jessica Wyndham, head of Sotheby's London jewelry department. 

"She first bought it in the 1980s as a costume jewel, cocktail ring and she has been wearing it around ever since," Wyndham said. "It's impossible to really date it, but the style of the diamond has notable characteristics similar to what you would expect from the 19th century," she explained. 

"She randomly took it to a local jeweler who said, 'This could be a diamond,' and told her to 'seriously get it looked at,'" Wyndham added. The ring's owner was searching impressive diamonds on Google when she found Sotheby's and reached out to Wyndham to get the process started. Once Wyndham was able to see the stone in person she decided to contact the Gemological Institute of America to have the gem identified officially. "They check the diamond and give a certificate confirming the color, clarity, size and weight," Wyndham said of the New York City-based company. The stone came back as a cushion-shaped diamond weighing 26.27 carats with an attractive color grade of I and impressive clarity grade of VVS2.

Sotheby's will start the low auction price at about $325,000 but Wyndham said the diamond could reach $454,000. The unique 26.27-carat white diamond will be part of a sale on June 7, 2017, that includes a diamond broach worn by former British Prime Minister Margaret Thatcher and other priceless historic jewelry items.

Shirley Temple's Blue Diamond

The blue diamond ring that belonged to child-star-turned-diplomat Shirley Temple is going up for auction at Sotheby’s next month.

Shirley Temple Temple began her film career in 1932 at the age of three and in 1934 she found international fame in Bright Eyes. She was well known for her bouncy curls and outgoing personality (she was cute as a button!). From 1935 through 1938 she was Hollywood’s biggest box office star. 
As Shirley Temple Black, she had a long career in public service and was the US ambassador to Ghana and Czechoslovakia. She was also appointed as Chief of Protocol by President Gerald Ford in 1976 and was involved in preparations for President Jimmy Carter’s inauguration. 
She died in February 2014 at the age of 85 at home in Woodside, California.

'Sunrise Ruby' Steals the Show at Sotheby's Auction

The “Sunrise Ruby,” a 25.59-carat untreated pigeon’s blood red-colored stone set a new world auction record for price paid for a ruby on Tuesday at the Sotheby's Geneva sale. The ruby was initially estimated to sell at between $12-$18 million but bidding soared to $30.3 million, demolishing the existing ruby auction record that was held by the $8.6 million sale of the “Graff Ruby.” The ring also set a record for the price paid for a jewel by Cartier. It was sold to an million to an anonymous buyer.
The high price of the ruby heavily contributed to the Sotheby’s Magnificent and Noble Jewels auction which the highest-ever total for any jewelry auction at $160.9 million, deposing the Christie’s November 2014 sale of Magnificent Jewels in Geneva, which totaled $150.2 million.

Also performing well but not meeting pre-sale expectations was the “Historic Pink." The 8.72-carat fancy vivid pink diamond sold for $15.9 million, below its pre-sale high estimate of $18 million.
David Bennett, worldwide chairman of Sotheby’s international jewelry division had this to say about the sale: 
“(The) record result is the reflection of outstanding quality of the pieces in the sale across the board,...The galleries have been brimming with collectors during our worldwide exhibitions, and this translated into lively bidding throughout the sale … with truly global demand for the finest diamonds, gemstones and signed pieces of the very highest order.”

The November 12th, 2014 Sotheby's Geneva auction was lead by a truly magnificent pigeon-blood colored ruby known as the "Graff Ruby".  The ring was originally sold at auction nine years ago and was purchased by noted jeweller Laurence Graff for a record breaking price. He later named the ruby "The Graff Ruby". 
In Geneva the ring again fetched a record breaking amount (selling for $8,600,410). The ring was part of the Collection of Dimitri Mavrommatis (16 pieces) which also included a rare 27.54 carat step-cut Kashmir sapphire, as well as several pieces by contemporary jewelers, Graff and JAR (who was represented by a pair of superb sapphire, ruby and diamond earrings).

The "Graff" Ruby information:
The piece was accompanied by Gübelin report stating that the ruby is of Burmese origin, with no indications of heating. The SSEF report together with a letter stating:
"The Graff Ruby...The described gemstones exhibits an impressive weight and purity, combined with a very pleasant shape and cutting style. The faint inclusions found by microscopic inspection represent the hallmarks of the reputed deposit of Mogok in Burma (Myanmar). The stone has been spared to exposure of thermal treatment and its clarity and colour are natural. Its vivid red, poetically referred to as 'pigeon blood' is due to a combination of well balanced trace elements in the stone, typical and characteristic for rubies of the Mogok gemstone tract. Natural Mogok rubies from this size, colour and clarity represent a great rarity and the Graff ruby with its combination of outstanding characteristics is a very exceptional gemstone."
