As Senior International Jewelry Director, Senior Vice President (US)

The international auction house Bonhams is pleased to announce the appointment of Brett O'Connor G.G. as Senior International Jewelry Director and Senior Vice President, US. O'Connor will also join the US Executive Team.

US-born O'Connor takes up his new position at the start of November based in Bonhams New York office.

O'Connor is a globally renowned auctioneer and leading senior specialist in the jewelry sector with more than 24 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 jewelry sales in Geneva, Hong Kong, London and New York and was responsible for sourcing jewelry globally, liaising with the company's top clients and advising on their collections. Prior to moving to Geneva, O'Connor was Head of Jewels in Hong Kong for Sotheby's.

During his impressive tenure in Geneva, O'Connor was instrumental in making Geneva the auction destination of choice for consignors and buyers. He was closely involved in the collections of Maria Callas, Gina Lollobrigida, Henckle von Donnersmarck and the forthcoming Jewels of Marie Antoinette 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 colored diamond earrings.

O'Connor's passion for jewelry 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 jeweler 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.

Bonhams Global Head of Jewelry Jean Ghika said: "I am delighted to welcome Brett to the team. He has an excellent track record and is extremely well regarded within the industry. I am particularly looking forward to working with him to further build our presence in the US and Asia, which are some of the most important and fastest growing markets for jewellery."

Brett O'Connor said of his appointment: "I am pleased to be joining Bonhams at an important point in the company's long history and excited to be returning to the US with a view to expanding the jewelry department's global presence."
