Coupe, Dionysio Miseroni (workshop of), c. 1630 - c. 1640
This variety of quartz was prized more highly than rock crystal for its golden yellow colour. Only a few vases made of this precious material are known, which because of the abstract shapes of the cutting are associated with the famous lapidary workshops of Ottavio and Dionyso Miseroni. Cameos have been incorporated into the luxurious mount, including several with portraits.
