Our gemologists carefully assess and interpret the data collected to plot a high degree of accuracy for the Color grade, Treatment, and Origin.

Origin Report

The Origin Report assesses the authenticity of gemstones, identifies whether they have undergone any treatment (e.g. heating), specifies origin where the gemstones come f rom and determines their trade color whenever possible.


The Identification Report assesses the authenticity of gemstones, identifies whether they have undergone any treatment (e.g., heating), and determines their trade color whenever possible.
