Brief history of Gemval

April 2003
A group of professional gemologists and mathematicians started work on the Computerized Gemstone Appraisal System. Initially, we planned to develop a web tool to evaluate natural sapphires. However, after testing dozens of statistical models, we discovered that the statistical approach to sapphire valuation could be applied to almost any gemstone variety. Thus, after a year of compiling data and testing, Gemval.com was conceived.
