Frequently Asked Questions

I would like to submit a rough stone for identification service, how do I proceed?

Thank you for your inquiry regarding rough identification services available at GIA Laboratories. GIA primarily analyzes rough material in conjunction with our Diamond Origin Program which requires the stone to come back for diamond grading after cutting and polishing (no physical report provided with the rough service). If you are seeking identification of a rough material we recommend that you reach out to a local university or museum to better assist you.
