Used equipment for grading stones

I’m looking for some used jewelry equipment for grading and
evaluating colored stones. I need good polariscope, refractometer,
and a good zoom microscipe with back field illumination. If you
know of any used equipment please pass on the info. It would be
greatly appreciated. Thankyou Steven Blank

Hi Steven- I have a bunch of gem equipment that I don’t use (or know
how to use). Please contact me at @Ted_Finesman. Ted
