Bonhams Jewellery auctions offer gemstones and jewels from names including Cartier, Van Cleef & Arpels, Boucheron, Harry Winston, Tiffany, Bulgari, Chaumet and Verdura. We hold over 40 auctions a year across all the key jewellery markets: New York, London, Hong Kong and Los Angeles.
Our auction record results include The Hope Spinel, which achieved the world record price per carat for a spinel sold at auction. We also achieved world record prices per carat for a Fancy Blue diamond and a Fancy Pink diamond sold at auction. Among the high profile, international collections that we have brought to auction are the jewels of Dame Joan Collins, Lauren Bacall and Jackie Collins.
We champion wearable art and works by 'artist jewellers' - from Andrew Grima, John Donald and David Thomas in the UK to Art Smith, Betty Cook and William Spratling in the US. In 2006, we curated the first auction dedicated to works by Grima, followed by a 100% sold private collection of Grima jewellery in 2017 and a successful sale of artist jewellery from the Crawford Collection in 2021.
