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.

Over the last several weeks, high intake at most of our locations has driven up turnaround times for grading services. We are taking every step to improve the situation as quickly as possible and expect to see an improvement over the next two weeks. We appreciate your patience.
