Manhattan Chapter: Pricing Color with Richard B. Drucker, GIA GG


Colored gems are difficult to price due to many variables, including inconsistent grading parameters among dealers and gem labs. This program will delve into many gemstones and the challenges with grading them, nomenclature for describing them, issues with treatments and identifications, and more. This will go beyond the big three in discussion.

Richard Drucker is the president of Gemworld International, Inc. in Glenview, Illinois. His credentials include: Graduate Gemologist of the Gemological Institute of America; Honorary Fellow of the Gemmological Association of Great Britain; Senior Member of the National Association of Jewelry Appraisers; and Senior Gemologist of the Accredited Gemologists Association.

As a third generation in the jewelry industry, he began a pricing publication in 1982 now known as the GemGuide, which is used in more than 40 countries and is the industry leader in gem pricing and market information. He became the owner of GemGuide Appraisal Software in 2002 and co-developed the World of Color nomenclature and grading system for colored gemstones in 2014.

Drucker received the Antonio C. Bonanno Excellence in Gemology industry award in 2006 and was awarded honorary fellowship in the Gemmological Asociation of Great Britain (FGA) in 2012. He serves as publisher, appraiser, consultant, lecturer and author, and has hosted five international gemological conferences that bring gemologists, jewelers and appraisers together from around the world.
