Mr Cherry added: “The Duchess of Cambridge’s eternity ring is a beautiful display of simple jewellery that so perfectly suits her notably refined taste.
“This minimalist ring features an estimated total of around 0.25 carats of round brilliant diamonds – each perfectly chosen to match in colour and clarity grades to ensure a continuation of white, bright sparkle.
“The thin ring is set in pavé style, where tiny ball claws keep each diamond in place. The width of the eternity band matches that of both Kate’s famous sapphire engagement ring and Welsh gold wedding ring and is a subtle addition of sparkle to her bridal set.
“Kate’s thin, pavé eternity ring is around 1.8mm and would retail around £1,250, making this one of the more affordable pieces in her extensive jewellery collection.”
