expert Natasha Raskin Sharp left her co-star "scared of the whole thing" after finding a chilling family heirloom.
Narrated by Tim Wonnacott, the series follows antiques experts who compete against each other to see who can turn the biggest profit over five programmes with an initial budget of £200.
During the celebrity edition of the BBC show, star Paul Gorton and winner Harry Clark went on a journey through the Scottish Highlands in a bid to find some hidden treasures.
This week, Paul was teamed up with Natasha meanwhile Harry battled it out with antiques expert Roo Irvine. But things took an unexpected turn when Natasha stumbled across a mourning brooch tucked away in a glass cabinet.
Calling over the fiery redhead, she showed him a brooch which featured braided human hair. Paul immediately recoiled in disgust at the item, as Natasha explained the history of the Georgian keepsakes.
She told him: "This is a mourning brooch. So, it was a way or remembering that person by having the human hair worn on you so that they were always with you. This should be nine carat gold so I'll have a look and see if there's any markings on it.
"See, a lot of Georgian mourning jewellery wasn't marked for gold, but this is the plaited hair and these are seed pearls. Do you like it?"
Paul honestly admitted: "It scares the living daylights out of me" as the expert added: "Well, see, some people find it quite dark but there is a big collectors market - and I'm one of them."
The reality struggled to understand the appeal to the morbid item, as he asked: "So people in the auction will just see that and go, 'Yes. I'm going to spent money on that?'"
The auctioneer simply replied: "If we can get that for a good price, that's a lovely little buy." Despite his disgust at the item, he decided to go with her decision, concluding: "Your passion shines through but yeah, I am a little bit scared about the whole thing, but let's do it."
Meanwhile, Paul discovered a nine-carat gold watch which Roo described as "beautiful". Turning to the show owner, they managed to purchase the two items for £240.
After their week-long travels, the two teams eventually reunited and showed each other their items - and it didn't take long before the fighting talk started to flow.
Picking up Paul's watch, Harry declared: "You'll need this to sell because your other stuff, I'm not feeling your other stuff." But this didn't faze Paul and Roo as she muttered: "We're going to win."
Things turned playful as Harry exclaimed: "Hod me back" before squaring up to his co-star. "Oh my goodness," Roo gasped: "Tash, it's kicking off." But it was clear the situation was completely light-hearted as Harry confessed: "I can't look at you without smiling".
Ultimately, it was Paul and Roo who came out on top at the end of the show with their loss of £81.20 beating Harry and Natasha's loss of £105.00."
