"The greatest compliment that was ever paid me was when[some]one asked me what I thought, and attended to my answer." Henry David Thoreau
What is life but a series of inspired follies? The difficulty is to find them to do. Never lose a chance: it doesn’t come every day!
George Bernard Shaw
“Nothing is often a good thing to do and always a good thing to say”. Will Durant.
We are pleased to inform you that GIA’s Topical Session, “"T131. Gemological Research in the 21st Century: Exploration, Geology, and Characterization of Diamonds and other Gem Minerals,” has been accepted for the technical program in Baltimore, Maryland, USA – for GSA 2015! In addition to Dona Dirlam, Jim Shigley, and Wuyi Wang of GIA, our distinguished advocates are Lee Groat, Thomas Stachel, Barb Dutrow, Howard Coopersmith, Nancy McMillan, and Skip Simmons. Last year’s session was a big success. Please consider submitting an abstract to this year’s session. The submission form is now “live” and can be found here: http://www.geosociety.org/meetings/2015/sessions/topical.asp
Please forward this link along to anyone who might be a potential submitter. The abstracts deadline is 11:59 p.m., Pacific Time, 11 August 2015. (I know this is arriving to the reference list late perhaps the deadline may be extended?
