" A society is about people; gems are the subjects that bring us together. The IGS has thousands of members on every continent, (except Antarctica of course.) They range from seasoned professionals to the merely curious.
Professionals join because gems are their favorite topic. We offer them the Professional Gem Reference, the Gem Pricing Guide, news, and advertising privileges. However, from the feedback we receive their favorite part are the technical articles. They tell us the articles are a good refresher and we frequently hear where they have learned something new. The professionals in our organization are important for sharing their wealth of knowledge. No one individual has the experience of the membership as a whole.
On the other hand, some of our members have no interest in working in the trade. They simply want to unravel the mysteries surrounding their prizes. Nowhere else can a person access so much information from an unbiased source. ..." more
