Ron Dupuis, F.G.A., G.J.
Dupuis Fine Jewellery Auctioneers Inc.

Ron Dupuis earned a Diploma from the Gemmological Association of Great Britain in 1979, a 'Graduate Jeweller' degree from the Canadian Jewellers Association in 1978 and 'Diamond Certificate' from the Gemological Institute of America in 1977. After apprenticing as an appraiser for a period of 4 years in a jewellery store that specialized in estate jewels he recognized Canada's potential for jewellery auctions. Thereafter, as a Director of Jewellery at Sotheby's from 1980 to 1986, Mr. Dupuis established jewellery auctions in Toronto with a special focus on Canadian private clients.

In June 1986, he founded an auction house in Toronto specializing exclusively in jewellery. Its mission is to provide a venue for fair disposition of fine estate jewels, diamonds and coloured stones from private individuals, estates and dealers. Based in Canada and renowned internationally, DUPUIS auctions are typically 80–85% sold by lot, often fetching prices above estimates in highly competitive bidding.

His knowledge combined with 32 years of auction experience is invaluable to both buyers and sellers. Ron Dupuis is recognized as an authority on the history of jewellery with his bi-monthly column in Jewellery Business Magazine. Any discussion of fine jewellery at auction in Canada would be incomplete without mentioning Ron Dupuis and his talented team at DUPUIS.
