Is there anyone with up to date knowledge of jewellery

[Dinoraw]

So I'm having to sell things for rent. My mom is an expert in jewellery but I can't tell her about this.
She bought me this for one of my birthdays and I'm not too sure if it's diamond or CZ? I can't imagine it would be CZ but I need to know what to list.

I've realised this is probably a stupid question but how would I know what it is? There isn't a hallmark anywhere :(

Take It to a jewellers... they will tell you.

Is there a retailers/ jewellers name on the box? (if it is the original box) it might give a clue as to whether it will be costume or real if there is. If there isn't a hall mark it unlikely to be diamonds.

Found out a hallmark on the clasp. It's white gold. An learnt how to tell diamonds from other stones. Diamond and white gold bracelet. Thanks both

Instead of selling, why don't you take it to a pawn shop and get a loan against It? Then, you'll have 6 months or something to go back and get it if things improve?

I never wear it. I have two really young kids who'd break it, thanks for the suggestion though
