(IDEX Online) - The Blue Belle sapphire and diamond necklace is to lead a Christie's New York sale next month with an estimate of $8m to $12m.
The tassel pendant features a 392.52 carat unheated, cushion modified, mixed-cut sapphire from the famed Ratnapura region of Sri Lanka, together with oval-shaped diamond terminals, and a brilliant-cut diamond neckchain, mounted in gold.
The estimate is well below the $17.6m the piece sold for at Christie's Geneva when it last changed hands in November 2014.
The sapphire was recovered in 1926 and was sold in 1937 to was sold to British motor magnate Lord Nuffield, founder of Morris Motors.
There were reports at the time that the gem would be gifted to HM Queen Elizabeth the Queen Mother on her coronation day, though this didn't actually happen.
"Sapphires of this caliber are extraordinarily rare," said Rahul Kadakia, Christie's international head of jewelry.
"This remarkable stone must be considered among the most prestigious colored gemstones to appear on the market in many years - truly worthy of any world-class collection.
Among other highlights at the Magnificent Jewels live auction on 17 June, is the Marie-Thérèse Pink Diamond, 10.38-carat kite-shaped fancy purple-pink diamond that is said to have belonged to Marie Antoinette.
It has recently been set into a contemporary ring by the Parisian jeweler Joel Arthur Rosenthal (JAR).
