Turnaround Time

Below are the current estimated turnaround times for diamonds and colored gemstones submitted to GIA Laboratories. Turnaround time is calculated from the date GIA receives the item to the date results are made available to the client. Secondary services and transit times are not factored into the estimate. Turnaround times are updated weekly.
