'The Blue Belle,' a 392.52-carat Ceylon sapphire with an estimate of $8 - $12 million
A fancy pink diamond with French Imperial provenance, Indian Mughal jewels and a 392.52-carat Ceylon sapphire are among the highlights of Christie's New York Magnificent Jewels auction on June 17.
An historic jewel of exceptional provenance is one of the premier lots of the sale at Christie's Rockefeller Center headquarters. The 'Marie-Thérèse Pink Diamond' has a storied past that has passed through French, Bavaria and Austrian imperial and royal families and may be linked to Queen Marie Antoinette.
The rare 10.38-carat kite-shaped fancy purple-pink diamond with SI1 clarity is believed to date to the mid-18th century, Christie's said.
As the story goes, Marie Antoinette entrusted her jewels to her coiffeur on the eve of her failed escape from Paris in 1791, hoping to one day reclaim them. The jewels were then passed down to her only surviving child, Duchess Marie Thérèse de Angoulême, and later to her niece, Duchess Marie Thérèse de Chambord. Though not known for certain, it is likely that this pink diamond was part of this inheritance, Christie's said.

'Generations later,' Christie's said, a will identified the diamond's next known owner as Queen Marie Theresa of Bavaria, who referred to it as 'a pink solitaire diamond from Aunt Chambord.' The gem was stored in a velvet case containing a hat pin bearing the Austrian Imperial Warrant—likely dating to 1868—the diamond's provenance reflects its imperial legacy, Christie's said. The gem last appeared at auction in Geneva in 1996, offered by a member of a European royal family. Since that sale it has remained out of public view.
In addition to its likely imperial provenance, the diamond has been set into a contemporary platinum ring paved with diamonds designed and crafted by famed American-Parisian jeweler Joel Arthur Rosenthal, better known as JAR.
The estimate for the fancy pink diamond ring is $3 million - $5 million, making it the number two lot in the auction.

Like the fancy pink diamond, this massive sapphire has a history shrouded in mystery.
The gem was unearthed in 1926 at Pelmadula, Ratnapura ('The City of Gems') in Ceylon, but the size and shape of the gem in its rough form is unknown, Christie's said. It had a 'highly prized peacock blue color and excellent clarity,' according to the documentation Christie's uncovered. It was owned by the well-known gem and jewelry dealers Macan Markar in Colombo.

Acquired in 1937 by British motor magnate Lord Nuffield. It is believed he planned to give it to Queen Elizabeth (later The Queen Mother) on King George VI's coronation. Instead, the jewel was sold privately and passed through several owners before appearing at Christie's Geneva auction in 2014 where it sold for $17.3 million.
The sapphire is the centerpiece of an elaborate 18k white gold necklace covered in round and oval shaped diamond. Its estimate is $8 million - $12 million.
In addition, the New York auction will offer three gem-set necklaces with historic Indian Mughal provenance.
A Mughal Antique Carved Emerald Necklace with an estimate of $2 million - $3 million
The first is a Mughal carved emerald necklace consisting of three carved Colombian hexagonal and two carved pear-shaped Colombian emeralds with an approximate total weight of 1,150 carats. The largest emerald of approximately 470 carats is inscribed with the name 'Ahmad Shah Durr-I Durran,' founder of the Durrani Empire of Afghanistan and northwest India. Its estimate is $2 million - $3 million.
A Mughal antique multi-gem and emerald necklace with an estimate of $2 million - $3 million
Similar to the first piece, is a Mughal multi-gem and emerald necklace featuring four Colombian emeralds weighing nearly 800 carats. The necklace is further adorned with a drop-shaped spinel bead, a baroque ruby bead and baroque natural pearls. Its estimate is $2 million - $3 million.
A Mughal three-strand spinel and natural pearl necklace with an estimate of $1 million - $2 million
The third piece is a Mughal three-strand spinel and natural pearl necklace with eight inscribed stones, in the Mughal tradition of memorializing gemstones to record their royal provenance. These spinels bear the names of some of the most powerful figures in history, including Muhammad ibn Tughluq-Shah, the Sultan of Delhi, the first Mughal emperor, Babur, and emperors Jahangir and Shah Jahan, Christie's said. The spinels have an approximate total weight of more than 2,000 carats. The estimate for the necklace is $1 million - $2 million.
In addition, the New York auction is featuring a collection of jewels from the estate of Anne Hendricks Bass, an American investor, documentary filmmaker, and art collector who was the former wife of billionaire oilman Sid Bass. The collection consists of 26 personal jewels that feature examples from Van Cleef & Arpels, Bulgari, Cartier and JAR.
