I know many gemologists rely on a Spectroscope and pritned reference books to identify gems. Is there a good Spectrometer that can do the lookups for me? If not, is there a good cheap spectroscope that I should be looking at for gemology? One that offers a USB connection to a computer should be good enough to write a database for lookup comparisons.
FWIW if people want the software and it doesnt exist I could write it. 40 years of experience writing software.
