X-Rays and Their Use in Gemology

DATE: Thursday, April 15th at 10:00 a.m. PDT

Did you know that X-rays not only reveal bones but have applications in gemology as well? X-rays are used to separate natural pearls from cultured ones and to assist in the origin determination of some gems. This technique is unique in that it can be used on opaque as well as transparent gems and is crucial to some aspects of gem identification. Find out more about X-rays with Nick Sturman, Consultant to GIA, in this latest GIA Knowledge Session.
