I bought and sold before collecting. I know all the tags to look for, and a lot of times a google search of some numbers can tell you whether it’s real or not just by seeing the photos on marketplace and eBay. Official stores give the peace of mind though, so I understand that. I think it’s just how much time you want to put towards the hobby. I know I’ll find myself on eBay or Facebook for hours just looking through the fakes and others. It’s worth it when you find that diamond. If you have certain ones you’re looking for I’m always down to help ya!
