In order to submit or pick up stones on behalf of your company, be sure you are pre-registered on a GIA laboratory account as an authorized representative or a principal of the company. If you are not already on the account, please have a principal of the company (owner/co-owner, president, vice-president, CEO, director or manager) log into their account to add you. From the client portal, they can easily add additional team members and their valid government-issued photo IDs.
You may also bring a signed and dated letter from the principal of the company, with their name and title, to the GIA Show Service Laboratory counter when you submit your colored stones. For additional information, please contact firstname.lastname@example.org.
Report Services Offered
GIA Show Service Laboratory report offerings differ per show.
Stones are tested on a first-come, first-served basis. The service time to complete your order can vary depending on when you submit your item, ranging from 24 hours at the beginning of the event to 72 hours or more as the show progresses. Service time may be extended at some shows if the gemological testing is not completed. These stones will be sent to a GIA laboratory location to complete the service, and shipped back to you after the show ends. If the Show Service Laboratory has reached maximum capacity, you will be notified prior to submission. However, we will continue to take submissions with the understanding that all testing will be performed at a GIA laboratory after the show.
Pick Up and Payment
When your service is completed, you will be notified by phone, email or text to pick up your stones and temporary reports. Final reports will be mailed within two to three weeks after the show. Client accounts cannot be billed, payment must be made when the service is completed. Payment methods vary at each event and may include one or more of the following: cash, credit card or wire transfer.
GIA customer service representatives and gemologists are available on-site to help and answer any questions. For more information prior to a show call +1 800 421 7250, ext. 7590 or +1 760 603 4500, ext. 7590 (outside the U.S.) or email your preferred location.
