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.
Ruby consistently demands some of the highest prices of all gems. In the past half-century, more ruby sources have been discovered, but some sources carry a strong association with legends, romance and consistent high quality that can affect the value of a ruby.
How Does it Work?
This seminar will introduce the main sources of ruby around the globe, their status in the market, and the methods the GIA Laboratory applies to determine ruby country of origin, including the utilization of traceable sample collections and advanced testing techniques in combination with decades of accumulated experience from gemologists and researchers.
This seminar is ideal for sales associates, retailers, investors, collectors and researchers. Familiarity with colored stone value factors is recommended.
