GIA is inviting Richard S. Brown, a leading expert in planetary gemology to present a talk on ancient astrological gems and talismans during its Gemstone Gathering in Bangkok. The event is slated on August 27.

Ratna-para-vidya or planetary gemology is an ancient Vedic belief system and practice based on the relationship between nine categories of gems and nine planets recognized as most important in Vedic astrology. Brown’s talk will include planetary gemology, based on the "Navaratna" or “Nine Gems” philosophy of Vedic birthstones.

Brown is a GIA graduate and founder of Astral Gemstone Talismans and the Planetary Gemologists Association. He holds over 30 years of experience studying gems in relation to astrology. His experience includes learning Sanskrit translations that related fine gems and astrology, when he lived at a north Indian monastery. He has authored 13 books and over 240 articles and has appeared in numerous television segments in Thailand.

The event is a free event and will be held at the Crowne Plaza Hotel, Lumpini Park in Bangkok.
