Polariscope Tutorial

I have 1 further questing in my pursuit of learning the trade as an amature hobbiest. If these various gem stones, and crystas or whatever you might be working with were cut differently with varying fascets and angles ect, would this affect how this test would turn out in terms of say an anistropic result or say maby a anamolous result?, or would the result stay the same no matter how the pice was cut. To me I would think the properties of this test would always remin constant regardless no?

This was really interesting to watch, slowly starting to learn more and more about gem prospecting and identification of all the many and various properties that makes them special. Thanks for the video. Cheers, IC.

I used to live in Peshawar, did not know there is a gem school. I could have studied there.
