Delicately hand-crafted, each piece of the Single Stone engagement ring collection is uniquely designed around a vintage center stone diamond. If you have your own vintage stone, the designer would be delighted to work on a special piece for you. The intricate details of the hand engravings are stunning, giving an authentic vintage feel to these antique inspired engagement rings. The collection features many styles, from classic solitaires with floral engraving like the one bellow to glamorous art deco engagement rings such as the one above. The collection starts at $1,800 and is available at Greenwich Jewelers.
