Marguerite 1735 diamond and sapphire engagement ring

EDITOR'S REVIEW

• Famous for its blue sapphire engagement rings, Garrard created the Duchess of Cambridge's sapphire and diamond cluster ring
• The 5.21 carat cushion-cut unheated Sri Lankan blue sapphire is held in place with four platinum claws
• Edging the sapphire is a rim of tiny round diamonds and beyond that is a curvaceous halo of 12 larger round diamonds
• The shoulders of the ring have also been set with strips of diamonds
• Total diamond carat weight of 1.08 carats
• In platinum
• Discreetly placed inside the band, next to the required hallmarks, is the signature of the British jewellery house

This ring is priced at £144,000
