Our Gemologists
Melissa Scarani, GG (GIA), FGA
Melissa has been an active gemologist who has worked in the retail market for more than 20 years. While working for top credentialed jewelers belonging to the American Gem Society (AGS), Melissa gained her first-hand experience with world-famous brands like Rolex, Breitling, David Yurman, David Webb, and many others. She also worked with fine antique jewelry for more than a decade, becoming knowledgeable about the different periods of jewelry and brands such as Tiffany, Mauboussin, Boucheron, Giuliano, Van Cleef & Arpels, Cartier, Buccellati, et als.
Melissa's passion for gems drives her to seek new knowledge continuously. Although she was already a GIA Graduate Gemologist, she expanded her expertise by earning the FGA title from the Gemological Association of Great Britain (Gem-A). As a result of her travels abroad, in particular her visits to mines in Thailand and Vietnam, she has gained even practical skills about gems and their origins and treatment.
