Why This Seminar?
Many treatments have been developed to attempt to enhance a diamond’s color and clarity. A treated diamond may still be a beautiful and valuable gem, and ideally, the treatment is disclosed during the sales process; however, that may not always be the case. Understanding how to identify these treatments is important to help protect the value of the gems for both buyers and sellers, as well as maintaining the trust between a customer and retailer.
How Does it Work?
This seminar will introduce the most common treatments applied to diamonds in today’s market, with a focus on the treatments that can be reliably identified using standard gemological tools. Using a camera-equipped microscope, instructors will demonstrate identification techniques and how they examine diamonds treated for clarity enhancement. More advanced color treatments, which will often require advanced instruments to identify, will be covered briefly.
This seminar is ideal gem and jewelry professionals, retailers, sales associates, jewelry enthusiast and appraisers.
Laser drilling allows access to internal inclusions which can then be altered to lighten dark inclusions and improve the apparent clarity of the gem. Laser drilled holes may be detected able under 10x magnification, but higher magnification may also be necessary. Two examples are shown. Left Photo: Vincent Cracco/GIA.
