Sotheby's and the Steinmetz Diamond Group created Sotheby's Diamonds – an important joint venture offering the rarest and most desirable diamond set in exquisitely-designed jewellery. Sotheby's Diamonds combines the expertise of Steinmetz in diamond cutting and polishing along with Sotheby's connoisseurship and international client base. The by-appointment only private service is available in London, New York and Hong Kong and will be extended to other major cities shortly.
