So I work at a thrift store/flea market that doesn’t accept donations but we go and clear out spots so we find genuine jewelry a lot of times. I’m new to this stuff since I just got hired a week ago, but other than diamond testers, I can only name gemstones by color and look.
I cannot tell apart CZ and real diamonds so I kinda need advice since I already have a diamond tester but it’s breaking on me since it’s like a couple years old.
If anyone has any advice on how to find out real diamonds of any size and color or certain gemstones without a tester. While I’m at it, if anyone has tips on finding real gold in rings, chains etc.

So I’ve been skating on ice for maybe 3 years now and self taught (getting a coach soon 🙏🙏) and I wanted to know if inline skates were a good option for off ice? I’ve seen hype around it and I’m honestly considering getting some inline skates just to get to school for fun, but I also want to ask if they’re similar enough that I can practice off ice moves on them, like foot work, spins, jumps, etc?

Also if anyone knows anyone who fits inlines in CT/MA/NY areas, I would appreciate it so much. And thank you to anyone who comments!
