For its 33rd Gemstone Gathering, the Gemological Institute of America (GIA) Thailand has invited Richard W. Wise, a graduate gemologist and president of R.W. Wise, Goldsmiths Inc., to share his experiences. The event is slated for February 24, 2010.

Wise holds to his credit a rich global experience as a goldsmith, also as an interviewer of leading gemstone experts. He has also authored a novel - The French Blue, written on the life of the 17th-century gem dealer Jean-Baptiste Tavernier.

The “Secrets Of The Gem Trade, The Connoisseur's Guide To Precious Gemstones,” includes Wise’s writings on variation of the Four C's in grading diamonds, which he calls “The Four C's of Connoisseurship” or the four factors for quality-grading coloured gemstones and pearls. At the GIA, gathering, Wise will speak on the history and application of the Four C’s in grading ruby and sapphire.

Attendees will be eligible to enter a drawing to win an autographed copy of The French Blue.
