The Sinkankas Symposium has been described as the most important gemological conferences in North America by respected authorities on gemstones. The annual event is named for John Sinkankas (1915–2002), one of the most distinguished and influential figures in gemology and mineralogy. Every year, presentations on a featured gem theme are given by specialists in diverse gem-related disciplines.
Organized by Roger Merk for 13 years (2003–2015), the Sinkankas Symposium is co-sponsored by the Gemological Society of San Diego (GSSD) and the Gemological Institute of America (GIA), with generous support from Bill Larson from the event’s inception. Prior to 2021, the one-day event has been hosted at the GIA worldwide headquarters and Robert Mouawad Campus in Carlsbad, California.
