GIA’s next Gemstone Gathering is on 26 November in Bangkok

BANGKOK – 24 November 2014 – Hexagonal geometry is encountered daily in nature, science, architecture, art and gemstones. Jeffery Bergman, founder and director of Primagem, will illustrate the important role hexagons play in mineral and gem formation, and how the geometric shape has influenced jewelry design during GIA’s (Gemological Institute of America) Gemstone Gathering in Bangkok on Nov. 26.
Bergman’s presentation will include a discussion on hexagonal mineralogy and asteriated gems, and how the hexagon shape has been used as a source of design inspiration in the jewelry industry. He will then review trapiche gems including “reverse” trapiche emeralds from Colombia, rare trapiche sapphires from Mogok, Burma, and more exotic stones such as trapiche strawberry quartz and trapiche garnet.
Bergman, a gem dealer with more than 40 years of experience in fine jewelry and gem mining, cutting, wholesaling and retailing, is the founder and director of Primagem in Thailand. His career has taken him to more than 60 countries and every continent except Antarctica. He has appeared on BBC, CNN, NBC, ABC and GEO, and has been featured in Time, USA Today, National Geographic, Gems & Gemology and Discovery Channel magazine. He is a regular guest speaker at seminars and gemological association conferences and universities.
GIA’s Gemstone Gathering, a free event, begins at 6 p.m. on 26 November in the “Crowne Room 1-3” on the 21st floor of the Crowne Plaza Hotel, Lumpini Park in Bangkok.
