Kate Middleton’s parents Carole and Michael have been married for over 41 years. Carole and Michael Middleton married on June 21, 1980 at the Church of St James in Dorney, Buckinghamshire.

But what did Carole’s engagement ring look like?

The Duchess of Cambridge’s mother has been spotted many times wearing her stunning engagement ring.

The jewellery piece is not dissimilar to her daughter, Pippa Middleton’s ring from husband James Matthews.

Photos of Carole at the Wimbledon Tennis Championship back in 2017 and 2019 gave a close-up look at her stunning rock.

It features a square blue stone in the centre surrounded by diamonds.

Although it does not have the same coloured stone in the middle, Pippa’s ring is also an art deco design.

Pippa’s also has a central stone set in a halo of smaller diamonds.

Diamond expert David Allen of 77 Diamonds spoke to Express.co.uk to discuss the details of Carole’s ring.

He said: “Carole’s ring is inspired by the art deco style of the 1920s and 30s.

DON’T MISS:

The Duchess of Cambridge’s iconic ring originally belonged to Princess Diana.

Carole met flight dispatcher Michael while she was working as a flight attendant for British Airways.

The couple welcomed their first child Kate in 1982, followed by Pippa in 1983 and their son, James, in 1987.

They raised the children in a Victorian house in Bradfield Southend near Reading, Berkshire.
