I have no idea if this is really legit or not but I have tested it on everything I know is real in my jewelry collection and everything I know is fake. So far it hasn’t let me down once. You just have to understand the instructions on the back for it to work properly and the paper it comes with.

Waited a little longer than usual. Was really excited when it arrived but the actual box it came in was already open and it’s missing a light cover. Two reds are there but the top clear light cover like it was tampered with.

This diamond tester works perfectly! I have no complaints. I’ve already tested diamonds and the fake ones I had sitting around… it knows the precise difference.

I don’t know if it’s just me but when I test it I feel like you could control it instead of it just giving you the real actual factual. Hell no it’s not real or heck yeah. I was gonna give it a one, but then I realized I could trick some people so I guess thanks no thanks
