If you have a gemstone you would like analyzed, we provide GIA® report services to our clients. Through this service, we will submit your gemstone to the GIA® laboratory in Carlsbad, CA or New York City, NY. Once your gemstone is received at the lab, a GIA® specialist will review your stone and generate a report. Typical report items include stone species, clarity, cut, and where ordered and applicable, origin.
Special Notice on GIA® Report and "Certification"
GIA® does not certify diamonds or gemstones. There have been websites claiming GIA® Certification on gemstones, however GIA® does not certify any gems as per their own website. Buyers should be aware of this as some retailers incorrectly offer certification services through GIA®.
GIA® reports provide technical information on characteristics of your gemstone that can be used for appraisal and insurance purposes. Gemstones and jewelry sold with a GIA® report tend to fetch higher prices because they have been properly identified by an independent and reputable gemological institution.
How It Works
After you place an order for a report, you will put together your gemstone and ship it to us at the address provided. Once we receive your gem, we place it into the required packaging per GIA® policy, and then we ship the stone to their laboratory and await analysis.
Typically results take about 2-4 weeks, sometimes longer. We usually received a preliminary report which we will share with you once completed. After the gemstone is completed in their system, it will then be mailed back to you directly.
The report is yours to keep in a safe place for appraisal and insurance purposes. Pricing varies based on carat size and whether or not an origin report is request.
If you are looking to have diamonds or jewelry-set gemstones analyzed and graded, contact us for a pricing quote and special handling instructions.
