If that's the one Hattie had on last night, she was recommending it as kids' jewellery. So long as the parents were all for it.
Personally, if I was going to spend multiple hundreds buying a diamond bracelet for my daughter, I would be: a) putting it away for her 18th, and b) wanting something better for the price than i3 diamonds and gold overlay. Nothing tells the recipient how much you love them more than inferior gems and gold plating.
