Antiques Roadshow guest tells expert 'behave yourself' as she learns true price of item

An Antiques Roadshow guest was left stunned on Sunday's episode as she learnt the true price of her family's stunning items.

During the latest episode, which was filmed at Thirlestane Castle in the Scottish Borders, one guest brought along two brooches and a pendant from her grandmothers for valuation.

Expert Susan Rumfitt was left impressed by the items, which included an opal and diamond brooch dated from 1890 to 1910, a pearl and diamond pendant from the 1900s and a sapphire and diamond brooch from 1970.

Valuing the items, expert Susan said the sapphire and diamond brooch from 1970 would fetch between £500 to £700, the pearl and diamond pendant from the 1900s would be valued between £1,500 and £2,000 and impressively the opal brooch would fetch between £5,000 to £7,000.

After learning the true price of her precious family items, the stunned guest exclaimed: "No, behave yourself! Wow, thank you very much!"

Before adding: "I'm absolutely flabbergasted and was delighted to hear such lovely news about the jewellery. No, I won't be having them remodelled, I'll be keeping them the exact same!"

It comes as Fiona Bruce recently revealed a brutal moment on the Antiques Roadshow which producers deemed too unkind to show to the nation but the star says it would have made amazing TV. Earlier this year, the TV star, 60, recalled a scene on the iconic show which has never made the broadcast as it was "too cruel" - but she claims would have made "great television". Fiona stood and watched as a poor man was told the brutal truth about a precious item that he wanted to get valued.

Chatting to , she recalled an excited smartly-dressed man arrived to the set to present a glass bottle that he purchased for £1,000 at an antiques shop. But things got a little uncomfortable when the show's glass expert examined the "antique" - and things took an awkward turn.

They told the owner: "I'm afraid it's an empty olive oil bottle. Tesco, circa 2008. It's worth nothing at all." Fiona knows that although the incident would have left viewers howling with laughter, but it was too unfair on the man to air it. She pointed out: "I suppose we could have broadcast it - but it was just too cruel. The guy was devastated. There's a tiny bit of my brain that realises it would have made great television. But it's just not what the show's about. Poor chap, poor chap. The thing is, if you come on the Roadshow we are not about to humiliate you. The thing about Antiques Roadshow is not to humiliate people."

Antiques Roadshow continues on Sundays at 8pm on BBC One.
