Dear Gem Lover,
We have put together a package of educational resources, information and services that are designed to meet your needs.
The focus of the IGS is, of course, gemstones. However, we recognize that there are many kinds of gemologists at many stages of learning. Here are the highlights of what is being covered.
GEMOLOGY
Gemology is the study of gemstones: what constitutes a gem, the terminology of gemstones, their physical and optical properties, and how those properties are used to identify gems.
Learning gemology does not have to cost thousands of dollars. As an IGS member, you are automatically enrolled in our gemology course. The only other charges are for testing. To learn about our Gemology Course follow this link.
GEM IDENTIFICATION
Knowing how to distinguish ruby from garnet, or diamond from CZ is an essential skill for anyone dealing with gemstones. Our resources include how to use the instruments of gemology and how to apply that knowledge. We have thoroughly illustrated articles that show optic signs, inclusions, and spectroscopic absorption patterns. In addition, we have several articles and charts to simplify tricky identification problems. (Click here for a sample.)
Theory alone is not enough to deal with the variety of gem materials you are likely to encounter. Our Gem Lending Program offers you a hands on learning experience using real gems. Our "What is it?" quizes take it a step further giving you real world experience.
To see a complete list of subjects, go to our Reference Library.
GEMSTONE GRADING
Another important aspect of gemology is learning how gems are graded. Grading expertise and knowing current prices, are required for successful trading and appraising.
To assist you in grading, we have an entire series of articles on the four “C’s” of gem grading. They give detailed information on both diamonds and colored stones. Again, theory alone is not enough to deal with the variety of gem materials you are likely to encounter. Our Gem Lending Program offers you a hands on learning experience using real gems.
To complete your knowledge base, we also have one of the most complete Gem Pricing Guide ever assembled. It includes the values of almost every gemstones you will encounter.
To see all that is available, go to our Reference Library.
LAPIDARY
The IGS recognizes that gem cutters are gemologists too and they have their own special needs. However, the articles on gem cutting are not just for the lapidary. Everyone will a gain deeper insight into gemstones from this information.
To see what we have on gemcutting, go to our Reference Library and follow the "Lapidary" link.
JEWELRY
Since most gems end up in being set in precious metals, we have an extensive section jewelry. Here we cover what you need to know about gems to set them, instructions on how to make jewelry, and how chose what is right for you.
To see our jewelry section, go to the Reference Library and follow the "Jewelry" link.
