Low temperature heat treatment of certain kinds of corundum has been a major concern to the industry in the past several years. This two-hour seminar will focus on how GIA Research develops more reliable ways to identify low temperature-heated stones from stones that have not been treated.
Participants will be guided by GIA researchers with expert knowledge of low temperature heat treatment of corundum and the processes used by GIA’s laboratories. Learn from illustrations, images, video and live demonstrations that let you see exactly what our experts see as they examine some of the very samples used in this research and learn to separate the sometimes subtle changes in inclusions that happen at these temperatures. Participants will have the opportunity to interact with the instructor during the seminar, and will receive digital reference material.
The number of attendees will be limited to ensure the best experience for attendees.
