Hi Mam thanks for sharing of Polariscope information it was nice since Christmas I haven't worked on any Instruments and you have freshan up my knowledge thankyou.
hello have a nice day What are the most important devices that can be purchased to accurately determine the type of gemstone. I work in selling gemstones, I don't want expensive devices because I can't buy them Thank you all
Polariscopes can be easily cheap. I've seen some online that you can buy for 10$. I would suggest looking at polariscopes with a price range between 17-30$.
