This large silver bowl by Tiffany was a wedding gift to the American-British socialite and heiress Mary Goelet and Henry John Innes-Ker, the 8th Duke of Roxburghe. Goelet was the daughter of the New York real-estate millionaire Ogden Goelet. When she married in 1903, her dowry was said to be $20m (around $500m in today’s money).
