I've not seen enough of Debbie to form an opinion, but Cherry always looks like she's angry and aggressive. I thought she was about to punch Toby in the face while he was talking the other day, based on the look on her face.
I quite like Toby though (even though he's starting to go down the slippery slope of making more and more dubious claims a bit more often now - something he once seemed to distance himself away from). I think he's the least shystery amongst a channel full of shysters. He does have a personality and a sense of humour too. He's not full of himself, like Dave and Jake. I would imagine that, outside of work, he's a genuinely nice guy to go down the pub to have a drink with.
I really hope Toby doesn't start going further down the dubious claims route though because he is the one guy out of the three so-called gem experts that does have some credibility. He does have a genuine background in gems, particularly Rubies and Sapphires. Unlike Troth, who seems to suddenly become an expert in whatever he's been offered to flog by the Chinese. When Charlie Barron was around, Dave was never put of air to talk about Pearls - but now Charlie Barron has gone, they can't wheel Dave out quickly enough to share his 'expertise' in Pearls with us. If Kati Elliott had to take 2 months off work, I have visions of Troth suddenly being wheeled to tell us he's a mascara and lipstick expert............
As for Jake, the least said the better. If he told me the sky is blue, I'd have to go outside to check because I wouldn't believe him.
