Research & Publications

Since its establishment in 1974, the EGL Platinum laboratory (formerly G.I.P.S. and E.G.C.) aims to be among the leading researchers in the fields of gems and gemology. As such, the laboratory team led by Menahem Sevdermish, FGA D. Litt., has been conducting researches and investigations covering a wide variety of issues related to the world of gems and gemology. Some of these researches were later published by the world-renowned industry-related magazines.

Below are some of the researches and articles issued by or assisted with the EGL Platinum team:

 

2003-2014 - Gemewizard – Digital gem color communication system
Gemewizard® is a pioneer in the development of software and hardware that provides solutions for professionals involved in the colored gemstone, fancy color diamond and jewelry industries, enabling the analysis, description and communication of color in gems. Using the extensive data accumulated by G.I.P.S. team (headed by M. Sevdermish), initial tests were conducted to verify the colors of gems. A major breakthrough in the research occurred in 1998 when the core program of a color grading system began to take shape. The suite of products developed by Gemewizard® is founded on the company’s groundbreaking color communication system called GemeSquare™. Users can accurately describe a gem’s color, and then communicate that information to other users, as well as to gemstone professionals who are not Gemewizard® users. The system has been endorsed by GIA® Education, and since 2006 has been incorporated into the GIA® curriculum.
