Types of GIA Reports (original) (raw)

Colored Gemstone Identification.

With a database of more than 100,000 individual colored gemstone samples, GIA’s expertise extends well beyond diamonds to colored gemstones. Utilizing decades of experience and analytical tools, we can pinpoint the identity and origin of many gemstones.

We also identify whether or not synthetics, simulants or stones have undergone treatment, including whether or not a gemstone’s color is natural or the result of a treatment.

The GIA Identification Report.

Identifies the type of gemstone and whether it is natural or synthetic, describes detectable treatments, details a full description of cut, shape, weight, measurement and color, and includes a photograph of the gemstone. While available for diamonds, this report is primarily for colored stones.

The GIA Identification & Origin Report.

Identifies the type of colored gemstone, natural or synthetic, informed opinion on geographical origin based on research and known samples, describes detectable treatments, details a full description of cut, shape, weight, measurement, and color, and includes a photograph of the colored gemstone.
