  • Raman spectrometer

    Not sure if this is right place for this topic. If not I guess some of the moderators will move.
    I would like to mention the gemological use of the raman spectrometer as means of very fast distinguishing if dyed or natural, cultured freshwater pearls as well as coral and conch pearls. Anyone else familiar with this? If not you can see a couple of nice articles written by Alberto Scarani GG and Mikko ?str?m FGA on this topic. I use a Raman spectrometer myself and can indeed recommend the tool as it is both fast and accurate. One drawback might be the price though.

    Yes, if the price didn't get in the way, what fun it would be to have one! Setting aside more serious use, think of all the found objects you could test. Alberto is a great guy.

        Both Alberto and Mikko are great guys. I use the Raman primarily for gemstones but the pearl side of gemology and photoluminiscence spectrometry is a very interesting field.

          Just for fun a comparison between PL-spectrum of Akoya, SS and Tahiti cultured pearls.

            Oh boy, I wish we could have one of those! It would make identification so much easier!
