A diamond solitaire ring estimated at $500,000-$700,000 will lead the first Bonhams New York jewellery auction of the year on April 17. The F, VVS2 round brilliant-cut diamond weighs 10.01 carats and is from a private collection in the US. The auction will also feature Burmese rubies, Kashmir sapphires, Colombian emeralds and diamonds together with a large collection of David Webb jewellery.
The sale, which consists of 133 lots, will also include an art deco ruby and diamond bracelet by Cartier, circa 1935, estimated at $80,000-$120,000; a ruby and diamond necklace by Bulgari estimated at $200,000-$300,000 and a ruby and diamond ring by Mermod & Jaccard estimated at $80,000-$120,000.
Caroline Morrissey, Senior Jewelry Specialist, Bonhams New York, says: “Rubies are far rarer than colorless diamonds, a fact that has been recognised in the world-record breaking prices they set at auction. Given the international appetite for specimen rubies together with a greater appreciation of this gemstone, we are anticipating keen interest in these pieces during our previews in New York, LA, Geneva and Hong Kong.”
Also going under the hammer will be a sapphire and diamond ring estimated at $80,000-$120,000; a sapphire and diamond pendant necklace estimated at $280,000-$320,000 and a diamond and sapphire bracelet by Bulgari estimated at $40,000-$60,000. Bonhams will also be auctioning a selection of emeralds originating from Colombia. This includes an emerald and diamond ring estimated at $110,000-$150,000.
Sixteen pieces of jewellery by American designer David Webb are also set to go under the hammer at the April sale. Most of the pieces were purchased directly from David Webb and were collected over a period of 20 years. It is the first time that they have come to auction.
