Exceptionally fine George II period diamond, rock crystal and enamel mourning ring for Jemima Grey, Duchess of Kent(1675- July 1728). The thin oval crystal sits on a tiny weave of hair flanked but two tapered old cut diamonds to each side. The enamelled shank reads 'Jemima Dutchess of Kent Ob 27th July 1728 AE 53 '.
