Brett O'Connor G.G. is Senior International Jewellery Director and Senior Vice President, US. Based in Bonhams New York office, O'Connor is a globally renowned auctioneer and leading senior specialist in the jewellery sector with more than 25 years' auction experience. Having worked extensively in Asia, North America, Europe and the Middle East, he joins Bonhams from Sotheby's Geneva where he was based for the last 16 years. He was one of the lead auctioneers for the company's major jewellery sales in Geneva, Hong Kong, London and New York and was responsible for sourcing jewellery globally, liaising with the company's top clients and advising on their collections.

During his impressive tenure in Geneva, O'Connor was closely involved in the collections of Maria Callas, Gina Lollobrigida, Henckle von Donnersmarck and the Bourbon-Parma Collection to name a few. O'Connor was also involved in bringing to market some of the most valuable and important diamonds and gemstones ever to appear at auction, including the Beau Sancy diamond, the Sunrise ruby and the Apollo and Artemis coloured diamond earrings.

O'Connor's passion for jewellery started at a young age. He attended the Gemological Institute of America in the early Nineties where he graduated in the top one per cent of his class with a GJG designation (graduate jeweller gemologist). He then went on to work for Christie's and Phillips in New York and Los Angeles before moving to Hong Kong and Europe for Sotheby's.
