WGI collaborates with SSEF institute


by Jo Black

World Gemological Institute and SSEF Swiss Gemological Institute have initiated a collaboration program intended to enhance the understanding of diamond treatments and their detection methods. World Gemological Institute research staff members have visited the SSEF Swiss Gemological Institute in Basel, Switzerland, to acquire frontier knowledge concerning the latest findings in the field of diamond treatment detection.

Among the technologies reviewed were advanced spectroscopic methods including laser induced photoluminescence, FTIR and UV/VIS spectroscopy. Also discussed were applications in the detection of color enhancement treatment in fancy colored diamonds and color removal in brown diamonds.

World Gemological Institute is aspiring to extend the scientific database available for research into the nature and complexity of diamond treatments. It is hoped that the joint effort will add significant insights into treatment detection and consumer education. This collaboration will include knowledge sharing in many aspects of diamond and gemstone research.
