A beautiful and unique vintage diamond engagement ring! The centre old mine cut is set in square shape corner claws. The old mine cut diamond is warm in colour appearing a warm ivory in some lights and pale yellow in others. It's a real chameleon, picking up on the colours around it. This diamond has a very steep crown, a super tiny table, and a wonderful large culet which reflects around the diamond making a kobize effect. The setting has a twist style design with a row of three diamonds crossing over two diamonds for a total of five accent diamond on each side. The shoulders narrow at a triangle design with a faint wheat style design decorating the edges around the entire circumference of this ring. Circa 1920s.
