Turnaround Time
Below are the current estimated turnaround times for diamonds and colored gemstones submitted to GIA laboratories this week. Turnaround times are calculated from the date GIA receives the item to the date results are made available and are counted as business days (i.e., weekdays excluding holidays). Secondary services and transit times are not factored into the estimate. Turnaround times are updated weekly and represent GIA’s best estimate for items submitted in the current week.
