célantest
Célantest is a proprietary method for assessing the authenticity of gemstones, particularly diamonds, developed by the Swiss company GIA. It is a non-destructive technique that utilizes specialized equipment to analyze the optical properties of a stone. The core principle behind Célantest involves the measurement of a gemstone's refractive index, which is a fundamental characteristic of any transparent material. Different gemstones have distinct refractive indices, and by accurately measuring this value, gemologists can differentiate between natural, synthetic, and imitation stones.
The Célantest system typically employs a combination of light sources and sensors to precisely determine how
While Célantest is a valuable tool in gemological laboratories, it is often used in conjunction with other
