Fearne Cotton, 39, has presented television programmes like Top of the Pops and Comic Relief over the years. She also became the first regular female presenter of the Radio 1 Chart Show, which she co-hosted alongside Reggie Yates for two years. Fearne has a particularly unique engagement ring, how much is it worth?

The blue and white small triangles are sat on a gold plated band. 

In some lights, the ring looks almost white, giving off an iridescent effect. 

While the exact cost of the ring is unknown, green opal band rings can range anywhere between £5,000 to £30,000.

Speaking about her ring from Jesse, Fearne said: “It’s got a lot of opal stones cut in diamonds around it and I get a lot of comments about it because it’s not your classic engagement ring.”

From one presenter to another, Tess Daly has a huge diamond from husband Vernon Kay.

How much is it worth?

Deborah Papas, Gemologist at Prestige Pawnbrokers of Channel 4’s Posh Pawn said: “Tess Daly’s engagement ring is a beautiful single emerald-cut diamond set in a very simple setting of platinum to show off its elegance.”

The huge engagement ring, chosen by Vernon comes at a hefty price too.

Papas continued: “It is believed to be between three and four carats, and of exceptional quality.”

Diamonds with a higher carat weight are rarer and more expensive.

The average engagement ring weight is 0.6 carats and so Tess’ is triple the UK average.

The expert added: “I estimate the value to be in the region of £250,000.”
