LGDR by GIA | Laboratory-Grown Diamond Report

In October of 2020, we introduced our redesigned Laboratory-Grown Diamond Report in a new digital-only format that reports 4Cs color and clarity specifications, replacing the previously-used descriptive terms and ranges. All LGDR reports include a QR code and a link to an educational page so you can learn more about laboratory-grown diamonds, including how GIA differentiates them from natural diamonds.

Laboratory-grown diamonds will be laser-inscribed with the GIA report number and the words "LABORATORY-GROWN" to ensure that consumers can clearly differentiate the product and fully understand their purchase. The LGDR, LGDR-Colored Diamond and LGDR-Colored Diamond Color Identification reports state that the stone was created by either the chemical vapor deposition (CVD) or high pressure, high temperature (HPHT) method. These three reports also state whether evidence of post-growth treatments to change the color was or was not detected, or if treatment was undeterminable.
