Rose cut diamond cluster ring. Set with fourteen cushion shape rose cut diamonds in closed back cutdown settings with a combined approximate weight of 2.00 carats, to an impressive quatrefoil design with one diamond set to the underside of the bezel, the broad smoothly conforming shoulders tapering through to a solid D-shape shank with engraved detailing and lug to reverse. Tested yellow gold, approximately 10g in weight, circa 17th century, accompanied by an Oxford Labs X-ray fluorescence report stating the composition of the metal.
During the 16-17th centuries, rings were not only worn on the finger, but also worn sewn onto clothing or attached from the neck or wrist with a bow. The lug at the reverse of this ring would have enabled this. See 'British Rings 800-1914' by Oman, C., plates 2-4 for portraits of the period showing off alternative ways of wearing finger rings.
