Celebrity Gogglebox fans could not believe their ears when they found out how much a gem on Antiques Roadshow was estimated to be worth.
And they were in stitches at actress Emilia Fox's mum Joanna's reaction to the whopping price tag on the gem.
The guest on the BBC show explained that she had been told by several jewellers it was an "inconsequential piece of costume jewellery".
"The style of it is actually quite ordinary, and you've been told by some jewellers, 'Take it away, it's valueless'," said host John Benjamin.
"You've been told by a number of jewellers it's an inconsequential piece of costume jewellery".
"If I was to tell you that whoever these jewellers were, they were talking absolute rubbish, would you be happy to hear that?" he asked.
"This is not a piece of jewellery of no consequence at all it is a piece of significant consequence because the stone in the middle is an absolutely enormous sapphire, cushion-shaped sapphire."
He continued: "Now I have to be honest with you, I've done this show for so long I've never seen a sapphire of this size ever bought onto the Antiques Roadshow, this is a real first time for me.
"If I were to take such an item of jewellery and consign it to an auction I would expect it to make between £40,000 to 50,000."
The baffled guest on the show revealed she was speechless because she was trying not to swear.
Joanne Fox erupted into an impression of what the woman wanted to say, shouting: "Ooh! F**K me!"
One viewer gushed: "Emilia Fox’s mother swearing still makes me cry with laughter! #CelebrityGogglebox ".
"Emelia's mum is funny 'F**k me'" added another.
"Emilia Fox mum on #Gogglebox is f**king brilliant," declared a third.
"Emilia Fox’s Mum saying “F**k Me” on #CelebrityGogglebox is surprisingly joyous. I think my Friday evening has just peaked!" gushed a fourth.
