The significance of the announcement of the entry of the latest diamond grading lab to the industry, De Beers' International Institute of Diamond Grading & Research (IIDGR), is discussed by JCK's Rob Bates. The IIDGR previously mostly issued reports for De Beers’ Forevermark brand diamonds. The uniqueness of the new lab different is that it relies heavily on technology for grading, De Beers spokesperson David Johnson tells Bates. It uses automated devices for all color grading from VS to I3, and is used as a “grader aider” for higher grades, Johnson explained.
Johnson says human graders will double-check the results: “If there is a discrepancy or the grade is near a boundary, the diamond will go through the system again.” Turnaround time is intended to be quick, he added. De Beers currently has three labs – in the U.K. Surat, and Antwerp, Belgium. The company is initially targeting the Indian, Far East, Middle East, and European markets and may station take-in windows in those markets, while a U.S.-based lab may be possible down the road, Johnson said."
