Hands-on session at Conclave 2019, Seattle, WAWe're kicking off this year's Conclave Session Spotlights by highlighting sessions presented by our Education Sponsor, GIA. The first session discusses the color-causing factors in natural diamonds, the next will take attendees on a microscopic adventure of gemstones, and the third covers the basics of jewelry forensics.


The Causes of Color in Natural Colored Diamonds
Sally Magana, GIA

Colored diamonds have long fascinated both consumers and gemologists. In this session, gain valuable insight on GIA’s ongoing research on diamond color and the color-causing factors in natural diamonds. You will also get an in-depth look at the major color groups for diamond (green, blue, pink, fancy white/black, and yellow) in GIA’s extensive database, which summarizes research results and the causes of color in these valuable and rare stones.


Microscopic Exploration of Gemstones
Nathan Renfro, GIA

The microscope is the most powerful gemological instrument available to the gemologist. As such, a significant amount of gemological information is preserved in the microscopic world of gems that is easily revealed with this instrument. Prepare to be taken on a microscopic adventure and explore the secret interiors and surfaces of a wide variety of gem materials. Features that can be observed under low-power magnification with standard lighting conditions will be covered, in addition to higher-magnification features using more advanced microscope techniques. Additional technical information on gemological lighting, photomicrography, and microscopy techniques will also be presented.


Jewelry Forensics Basics for the Appraiser
Al Gilbertson, GIA

While jewelry appraisers go through a process to identify, analyze, and assess the quality and nature of an item, is it comprehensive and systematic? Many know only certain aspects of manufacturing and are only able to recognize a narrow range of certain specific make traces. GIA has a framework that will guide you in identifying areas where you need to gain more exposure. Through this lecture and hands-on session, you will learn “jewelry forensics” basics, including how to identify hand-fabricated components, cast components, CAD/CAM manufactured components, and cast-in-place gemstones.


Mission Statement

The American Gem Society (AGS) is a nonprofit trade association of fine jewelry professionals dedicated to setting, maintaining and promoting the highest standards of ethical conduct and professional behavior through education, accreditation, recertification of its membership, gemological standards, and gemological research.

The Society is committed to providing educational products to inform and protect the consumer and to contributing to the betterment of the trade by creating industry standards to protect the jewelry-buying public and the fine jewelry industry as a whole.

AGS Laboratories, founded to support the AGS mission, is a nonprofit diamond grading laboratory with a mission of consumer protection.
