Separation of Natural and Artificially Colored Diamonds
Got diamonds? No problem. The AGTA Gemological Testing Center can identify the nature of the apparent color, or lack of color, in a diamond. UV/visible low temperature spectroscopy is used to analyze colored diamonds and to determine if the color is natural or due to artificial irradiation. The AGTA GTC's Raman micro-spectroscopy unit is employed to examine colorless diamonds that are suspected of being decolored by High Pressure High Temperature (HPHT) treatment.
