The accessory was a family heirloom that originally belonged to the guest's great-grandmother.
On Antiques Roadshow, a guest was shocked to learn that a family heirloom diamond brooch, initially believed to be fake, was valued at £12,000. In a separate US episode, a guest discovered a Rolex X Tiffany watch gifted by his uncle in 1975, which he wore daily, was worth $50,000 due to its original features.
