Brecken Branstrator (pictured), the former senior editor of National Jeweler, is becoming editor-in-chief of the GemGuide, the bimonthly gemstone publication.
Stuart Robertson will become president of Gemworld International, GemGuide’s parent company. In his new role, Robertson will oversee Gemworld’s day-to-day operations.
Richard Drucker, who founded Gemworld in 1982, will become its president emeritus.
As editor-in-chief of GemGuide, Branstrator will coordinate the content and editing of each issue. She will continue to be based in New York City.
Branstrator first joined in National Jeweler in 2013. A Graduate Gemologist, she has been nominated for a Women’s Jewelry Association Award for Media Excellence and a Jewelers of America Gem Award for Media Excellence.
The GemGuide provides wholesale pricing and market information for gem dealers, retail jewelers, and appraisers in more than 40 countries. In 2023, it will expand its coverage into the mineral trade, auction results, and fair-trade gem trends, Robertson said in a statement.
Robertson joined the company in 1998 and has served as its research director for more than two decades. He is the codeveloper of the industry course Corundum Treatments and Pricing, a senior member of the National Association of Jewelry Appraisers and chair of its conference committee, and the immediate past president of the Accredited Gemologists Association.
Drucker founded the company in 1982. In 2002, he expanded it by launching the GemGuide Appraisal Software for jewelry appraisers. In 2014, he codeveloped the World of Color, a comprehensive color grading system for colored gemstones. Gemworld has also hosted several World of Gems conferences.
Both Robertson and Drucker have won the Accredited Gemologists Association’s Antonio C. Bonanno Award for Excellence in Gemology.
