These certificates are provided by the Gemological Institute of America (GIA), a reputable and independent non-profit organization. To obtain the certificate, the gemstone or ring will be sent to the GIA laboratory for grading. This process typically takes 4-6 weeks in addition to the standard production time.For gemstones that are already set in the ring, their carat weight will be approximated since they cannot be individually weighed.

As for sapphires, the standard report will be the Colored Stone Identification Report.
