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.

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 🙏

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

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

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
