Why This Seminar?

The value of high-end colored stones can increase dramatically based on their origins, which is why ‘country of origin’ has become the most important value factor to consider, in addition to the quality factors of individual stones such as color, size and shape. Sapphire is one of the most challenging gems to analyze for country-of-origin determination due to its unique chemical properties and significant overlap of inclusion scenes across multiple sources.

How Does it Work?

This seminar will introduce the main sources of sapphire around the globe, their status in the market, and the methods the GIA Laboratory applies to determine sapphire country of origin, including identifying inclusion scenes, trace element profiling and spectroscopic analyses.

This seminar is ideal for sales associates, retailers, investors, collectors and researchers. Familiarity with colored stone value factors is recommended.

What You'll Learn

  • The main sapphire sources around the globe and the microscopic features that are characteristic for each.

  • Familiarity with the advanced testing modern gem laboratories use to help determine country of origin for sapphire.

  • The complications and challenges involved in sapphire country of origin determination.

Participants will be provided a digital reference guide, links to important sapphire country-of-origin determination articles, a sapphire inclusion chart, and are encouraged to ask questions as they are guided by a GIA researcher who will share their expertise through illustrations, images and lecture.
