DIANA Oval Cut Blue Sapphire Engagement Ring

DIANA Oval Cut Blue Sapphire Engagement Ring


This engagement ring is inspired by the iconic jewel of Lady Di, which is now proudly worn by the Princess of Wales, Kate Middleton.


This cathedral-style ring with prongs tied at the base of the gallery contains an oval-cut sapphire, symbolizing strength and freedom, with a halo of white moissanites surrounding the center gem, representing protection and security.


The model can also be made with white moissanites, colored moissanites, rubies, emeralds and laboratory diamonds.


The band is 2.6mm at its widest and tapers down to 1.6mm to give the center of the ring more prominence. The halo contains moissanites of 1.5mm diameter each.
