Gem-ID Report
A Gem-ID is essentially a gemological report which discloses much more information than the usual classic report. This report can be either in or out of the setting.
A Gem-ID report will also show several photographs of the inclusions and the graphic representation of 3 or 4 types of spectroscopy in order to give the tools to identify a gemstone, even after recutting.
The combination of inclusion mapping and spectroscopic measurements gives you a fingerprint of your gemstone, much like a human fingerprint, as inclusions are unique to each and every gemstone.
Some gemstones, if internally flawless, are not suited for this method. Nevertheless, very often inclusions can be found at a 100x magnification or more. The best candidates are emeralds due to their more varied inclusion pattern.
Gemstones are best inspected in their unmounted state, but in many cases removing a gemstone out of its setting can prove to be risky, especially with vintage, antique or historical objects. Therefore I personally prefer to inspect the stone in the setting when possible. If the stone does need removing, this may only be done by a master setter with many years of experience.
