"This ring is a show-stopper. The natural old european diamond is exquisitely cut and beautifully bright. It is well proportioned with large facets creating intense fire and scintillation. The reverse holds its own too, with fine foliate engraving. This ring would be perfect to mark an engagement or very special anniversary."
