An Antiques Roadshow expert has revealed the astonishing true value of a brooch purchased for just £1 at a car boot sale, leaving its owner stunned.

Filmed at the picturesque Alexandra Gardens in Cardiff, jewellery expert Joanna Hardy met with a guest whose remarkable collection was mostly sourced from car boot sales.

The owner revealed her talent for discovering hidden gems among ordinary trinkets. When asked by Joanna where she typically buys her jewellery, the guest smiled and replied: "A car boot."

Among the standout pieces was a delicate blue flower brooch, purchased for a mere £1 because it was broken. Joanna could hardly believe the price, exclaiming: "A pound!"

Examining the item closely, Joanna noted: "It is broken, you're quite right, you can see that it's come away."

However, the damage didn't detract significantly from its value.

Joanna explained the fascinating origins of the piece, revealing that the brooch’s flower petals were originally made around 1900 to 1915 as shirt studs, later converted into a brooch.

She described the brooch, set with beautifully calibrated sapphires and diamonds, as "absolutely exquisite".

Joanna then delivered the astonishing valuation: "You'd probably be looking at about £3,000 to £4,000."

The owner was visibly overwhelmed, exclaiming: "What! Good grief. Oh my days."

Another remarkable find in the guest’s car boot collection was an emerald necklace. Bought for just £3.50, Joanna confirmed it was indeed crafted from 22-carat gold with genuine emeralds, valuing it at approximately £800.

Joanna also appraised two additional brooches from the collection. One circular, 18-carat gold brooch with a central diamond, bought for just £2, was valued at £1,000.

A flower-shaped brooch featuring three diamonds, bought for a similar price, was valued between £800 and £1,200.

Joanna couldn’t hide her admiration for the guest’s incredible talent for spotting valuable jewellery.

"Frankly, you've done extremely well," Joanna praised, clearly impressed with the modest prices paid for such valuable pieces.

Laughing, the jewellery expert joked: "It never happens to me, I tell you."

The guest also showed Joanna two rings purchased from a shop twenty years ago for similarly modest sums.

One ring particularly caught Joanna's eye, identified as a creation by celebrated post-modernist jeweller Alan Gard.

"It's very highly collected, 18-carat gold with diamonds," Joanna said, giving it a valuation of around £3,000 to £4,000.
