GIA has never used this grade and has no plans to use it in the future. If the owner of a diamond has a report from a lab where the SI3 grade was assigned and would like to know how GIA would grade the stone, send the diamond to GIA’s laboratory for a diamond grading report. Please contact the laboratory offices to obtain information about fees and how to submit the diamond: GIA Gem Laboratory, Carlsbad, California, (800) 421-7250, ext. 7590, e-mail: gtravis@gia.edu; GIA Gem Laboratory, New York City: (212) 221-5858, e-mail: cindy.ng@gia.edu.
