Pippa Middleton and her husband James Matthews stepped out last night in London. They were photographed leaving the Henry Van Straubenzee memorial fund’s Christmas carol service at St Luke’s Church Chelsea.
The ring features an Art Deco style halo style, with large channel-set diamonds.
It is either platinum or white gold, and the centre diamond is an Asscher cut diamond which was estimated to be upwards of three carats.
At the time of the engagement David Christopher Allen, Creative Director of 77 Diamonds, told the Telegraph: “It is Art Deco in style with an octagonal halo of round diamonds surrounding what looks to be a 4 carat Asscher cut diamond.
“Asscher cut diamonds are step cut inside, which means there are fewer facets than standard shapes such as round or princess square cuts.
Kate Middleton is the wife of Prince William, second in line to the British throne.
When he proposed to his now wife, the prince opted to use his late mother Princess Diana’s engagement ring – a stunning sapphire set in diamonds.
The move may have inadvertently boosted the value of the royal ring, which is now worth almost nine times its original value.
The ring was originally bought for Lady Diana Spencer in 1981, and cost an eye-watering £28,500.
