Great. Exactly as described and is easy to bring everywhere. Functions perfectly. Arrived safely packaged and fast.

totally what they say it is

When you look through the scope you see two tiny squares, and I mean tiny! Like the size of your fingernail when you hold your arm all the way out.For my known gems I am able to tell single from double refraction, but some were very difficult to tell because of the small image.

This is a very good tool. I’m a Gemologist and I really like this must have tool.

So far so good.

Sturdier construction than I imagined, it has a decently thick metal body and I don’t worry about dropping it in a pocket. Works about as well as any other dichroscope.I will say that if small size isn’t a necessity then one of the small photography lights that’s very diffuse light with a polarizing sheet on top tends to work better.But for small size, this with a loupe and a penlight can identify a lot of stones in experienced hands while fitting in a pocket.

I thought it was fantastic to determine if the gemstones I purchased were genuine

Oh so cheap. It is what it is but it’s murder to use.
