Gem-A Education: How to use the refractometer

The refractometer is an essential instrument for gemmologists looking to identify gemstones. It can be a tricky tool to master, but if you learn the correct technique it can help you to identify a wide number of gemstones.
This video will cover the correct use of a refractometer, how to get an RI reading from a stone, and the possible results that you will see when testing. Watch this video to help you get to grips with the practical use of this gemmological instrument.
This video is brought to you by Gem-A education in association with Julia Griffith FGA DGA EG.

Your speech is full of energy ,Awsem🙏🌷🌻

at minute 6:31 ...turn the gemstone 360 degrees. I'm flumoxed. As a pilot we tease others telling stories about running into thunderstorms and turning 360 degrees to get the heck out of there. Maybe 180 degress would be what's wanted here too. And I am thankful for the presentation.

[@Mitch.Wasserman]

I see your point, but I believe what is intended here is to BEGIN rotating the specimen 360 and STOP when the R.I. lines are furthest apart.

Hello, have a good day, is there a table for reading gemstones? For example, when examining any stone on this device and the number 1.55 or 1.6 came out, for example, is there a table that matches the numbers to know the type of stone. Thank

[@SayaraDaCostaSoares]

Very knowledgeable as usual, but I feel like for the amateurs as well as for the students in gemology, extending the content of the video to the cabochon spot reading aspect would have complete this already academically well-explained vidéo. But that’s just my two cents on it. Thank you 🙏

[@emalireginamani2867]

Great job

[@wasanthatheswa1129]

Great Explanations : How much will be good & quality R I meter ?? Thank s

[@MikeDavis-on4kf]

Does the gemstone have to be cut, polished, clear, or prepared beyond a rough gemstone?

[@yzavahir]

Thanking you

[@yogawithcarlos]

this is a really good video. I have a question, my refractometer got a tiny crack on a corner of the prism, and I was wondering if it's now damaged. Many thanks
