In this testimonial, we travel to The Basel University Earth Science Institute, where we talk with Henry A. Hänni, Dr., FGA, Professor Emeritus of Gemmology and retired director of The SSEF Swiss Gemmological Institute in Basel, Switzerland. Prof. Dr. Hänni discusses the advantages of using a Portable Raman system like the GemRam from B&W Tek for Gem identification and verification.
