Bonhams offers rare coloured gemstones in London jewellery sale
Rare coloured gemstones are set to sparkle in the forthcoming Bonhams London Jewellery sale.
Amongst the most notable lots is a pair of late-19th century earrings featuring cushion-shaped Kashmir sapphires surrounded by old brilliant-cut diamonds.
Weighing 7.96 carats and 7.92 carats respectively, the sapphire earrings were formerly owned by a European princess and are expected to sell for £500,000-£800,000 ($760,000-$1.2 million).
Another highlight is a ring by society jeweller Andrew Grima, who designed pieces for the likes of Queen Elizabeth II, Princess Margaret and Jacqueline Onassis during the 1960s and 70s. Dating from 1971, and featuring a fancy greyish-blue, 2.97 carats step-cut diamond, the ring is expected to sell for £500,000-£700,000 ($760,000-$1.1 million).
Further Grima pieces on offer include a gold and amethyst ring dating from 1969, and a gold, tourmaline and diamond necklace and earclip suite created in 1968.
A number of exquisite diamond rings will cross the block, including an Asscher-cut 14.24 carats white diamond ring valued at £250,000-£350,000 ($380,000-$530,000), and a 5.02 carats cushion-shaped white diamond ring priced at £220,000-£280,000 ($330,000-$430,000).
The sale will also feature jewellery from some of the world's most renowned makers, including a Cartier diamond brooch made circa 1934; a diamond 'Cocktail Fizz' necklace by De Beers; and a ruby and diamond ring by Graff.
"Bonhams has declared 2015 the year of the coloured stone and in this final sale of the year we are able to showcase an exceptionally rare fancy greyish blue diamond, alongside Kashmir sapphires, and Burmese rubies, widely acknowledged as the finest and most desirable in the world," said Jean Ghika, Director of Jewellery for UK and Europe for Bonhams.
The Bonhams London Fine Jewellery sale takes place on Saturday December 5th.
