Surrounding the central sapphire are 16 hand set old mine cut diamonds totalling 1.50ct approx which complete the timeless 'Princess Diana' style halo to full effect. The gallery is beautifully carved adding that extra sign of quality to the ring. A fabulous early 20th century antique ring that would make for a truly unique engagement ring.
