James Nicholson FGA, DGA

Deputy Chairman, International Head of Jewellery, Silver and Watches | 集团副主席,珠宝、腕表及银器部国际主管

James Nicholson has over 30 years’ experience in the Jewellery trade.

James graduated from the School of Slavonic & Eastern European Studies, London University, in 1989.

His career in jewellery began when he joined Mappin & Webb as a management trainee and in 1991 he was appointed jewellery specialist at Bonhams where he gained his Fellowship of the Gemmological Association of Great Britain and diamond grading qualifications.

James joined Dreweatts in 2005 after running his own jewellery dealing business. Over his 14 years at Dreweatts James has handled the sale of many important jewels, coloured stones and natural pearls, watches and historically important silverware and objects of vertu. James’ personal highlights include:

  • A Russian Imperial gold and diamond presentation box by Fabergé containing a miniature of Grand Duke Sergei Alexandovich Romanov sold for £130,600 in 2005
  • A Russian purple guilloche enamel desk clock by Fabergé sold for £192,000 in 2008
  • A two row natural pearl necklace sold for £152,500 in 2011
  • A 1960s gold and enamel ‘Serpenti’ bangle watch by Bulgari sold for £84,300 and a sapphire ring by Jean Schlumberger sold £117,800 in 2014
  • An 18th century gold and specimen stone Steinkabinett box by Johann Christian Neuber sold for £186,000 in 2015
  • A pair of late 17th/early 18th century silver parcel gilt figure groups by Abraham Drentwett II, Augsburg, previously from the Chateau Jehay, Liege, sold for £179,800 in 2017
  • An impressive Edwardian aquamarine brooch, previously the property of Nancy Witcher Langhorne, Viscountess Astor CH, MP (1879-1964), sold for £67,500 in March 2019

James has also targeted a new generation of buyers at auction through the introduction of the collecting areas of Luxury Accessories and Fine Pens. This initiative led to the highly successful single owner sale of handbags and luxury accessories, December 2016 - the auction ran for 12 hours due to the intense interest from bidders. James also curated the three-day auction ‘East meets West’, January 2018, featuring 750 lots of luxury accessories and art works from around the world which totalled £1,168,240.

Since 2010 James has developed Dreweatts’ business activities outside the United Kingdom, notably in Italy and Spain where Dreweatts’ presence has been boosted through the provision of client services to Italian and Spanish consignors and buyers.  James also holds regular valuation and consignment events in Rome, Milan and Malaga and other European cities.




1989年毕业于伦敦大学学院的斯拉夫和东欧学专业,James在珠宝行业从业已逾三十载。1991年他作为管理训练生加入英国皇室御用珠宝品牌Mappin & Webb,之后便接任邦瀚斯的珠宝部专家,并取得了英国宝石协会的会员和钻石鉴定师的头衔。
