    Gem-A Refractometer For Ri & Birefringence?

    My goal here is to "zero in" on the colored "gem identification" using RI and Birefringence

    That will tell you what right away? Its DR OR SR> I can see that with a loupe. I would like to get exact Birefringence numbers. I await your response. Thanks Neil!

    Gem-A Refractometer For Ri & Birefringence?

    Just found sitting next to my microscope....One says Polarizer the other not. I assume use the one that says polarizer? Next question, It’s too big for the ocular should I just rotate on top of the ocular? Does it matter which side to my eye which side to the refractometer?

    Gem-A Refractometer For Ri & Birefringence?

    This is the position I had the refractometer for RI readings…. The RI readings were spot on. Never took off the eye piece, never rotated, and never pulled out or extended the ocular like in the images above...
  8. Sotheby's: David Bennett calls “the find of a lifetime.†Gemological Institute of America describes it as possessing the exceptional quality and transparency “commonly associated with Type IIa diamonds. I call it amazing!

    Lesedi La Rona: Is It 1,111 Or 1,109Ct?

    TOMRA Sorting's XRT equipment recovers world’s largest diamond in over 100 years. I believe 6 machines were purchased by Lucara...Above pictured is what they look like!

    Lesedi La Rona: Is It 1,111 Or 1,109Ct?

    But why is there a discrepancy in the stones carat weight. Lucara diamond mine (owner), GIA - The world's foremost authority on diamonds, Or Sotheby's (the greatest auction house in the world)….1111 or 1109CT?

    12 Carat Red Diamond

    JOJO - I would bake a cake and stick the 12CT red specimen on the top ie: (a cherry) then smack yourself in the face with it and see how it tastes…I hear this is a great way to test for genuine diamonds. Cheers matey!

    Did I Get Scammed?

    Lastly but not least use your eyes, and brain. No matter what 3-4 letter acronym is listed on the report including GIA/AGS.

    Did I Get Scammed?

    There is nothing wrong with an EGL, GCAL, IGI, HRD....or whatever. Any reports that represents the highest standard of reliability, consistency and integrity, are solid reports. Ie: GIA/AGS - Everything else should be taken with a grain of salt or 2 or 5.

  21. I have a question about DiaVision by Sarin. Iam trying to learn about diamond cut quality. Does DiaVision provide a good solution for determing if a stone is well cut? Thanks for your help. Regards Ron
