The definitive answer is the Infra-red Spectrometer. Quoting from the Mason-Kay website: http://www.masonkay.com/jade/whatisbjade.php
“In 1990 the Gemological Institute of America developed
a technique that definitively, and in a non-destructive manner,
can test for the presence of polymers within a jade’s interior:
infra-red spectroscopy. Polymers leave a tell-tale trace in the
infra-red spectrum. A machine called an infra-red spectrometer
can detect this trace quite clearly. Mason-Kay is currently
the only commercial firm in the United States equipped with
its own infra-red spectrometer since 1995. Mason-Kay is well
known for its testing and evaluation services to the jewelry industry.”July 2, 2015 at 8:07 pm #198750
