Colored Stone Reports
GIA colored stone reports describe the type of gemstone, if your stone is natural or synthetic, and if there are any detectable treatments. When determinable, origin will be provided for certain stones. Included in all reports is the gemstone cutting style, shape, weight, measurement, color and a photograph of the stone. Multiple security features on GIA colored stone reports ensure their authenticity. Loose or mounted gemstones may be submitted for these services.
