GIA has organised a seminar “Screening for Treated and Synthetic Diamonds: A Review of Existing Technologies” for participants  at theHong Kong Jewellery & Gem Fair, being held from September 15-21,  2014.

The seminar will be conducted by Dr. Wuyi Wang, GIA’s director of research and development, who will expound on “the technologies used to screen for treated and synthetic diamonds” on Sept. 16th.   

“Undisclosed treated and synthetic diamonds, particularly in melee sizes, are a concern for the industry,” said a GIA note.  “Wang will present on how GIA is addressing these concerns, as well as the current status of diamond treatments and synthetics . All GIA laboratories, with experienced staff and specialized equipment, screen all diamonds submitted for grading for treatments and synthetics. In addition, GIA developed and made available the DiamondCheckTM device, which can quickly and accurately differentiate natural, untreated diamonds in the D-to-N range from those that are potentially treated or synthetic”.
