Heavy Duty Calcite Dichroscope Gemstone Tester Trichoic Pleochroic Colors Gemstone Identification Gemstones Gemological Testing Diamond Jeweler Tool Metal Body Gemology

Use for gem identification. Well priced and works well. Easy to use and arrived quickly.

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.

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.

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

Sturdy and accurate. This item is a steal. Priced to sell and well made. Makes identifying gems that much easier.

totally what they say it is

Not sure how to use

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