Magnification is a tool used to check diamond quality by allowing a more thorough inspection of diamonds. It helps in identifying blemishes and anomalies, such as inclusions, feathered wisps, or scratches on the diamond's surface, which may affect its value. Increased magnification is essential in distinguishing real diamonds from fake ones.
Electrical conductivity is another tool used to check diamond quality, particularly in differentiating real diamonds from moissanite, which can be challenging to distinguish using heat-based diamond testers. A tester that utilizes electrical conductivity can help determine diamond simulants from genuine diamonds more accurately.
Laboratories use various techniques and instruments to determine a diamond's origin and quality. Some of these tools include spectroscopy, microscopy, luminescence under shortwave ultraviolet light, DiamondSure, and DiamondView. These instruments help identify synthetic diamonds and differentiate them from natural ones based on their color, production method, and imperfections.
CVD diamond testing machines are designed to differentiate natural earth-mined colorless diamonds from lab-created or synthetic ones. These machines use ultra-violet short waves instead of heat and electrical conductivity to test diamonds within seconds, providing assurance that the diamonds are genuine and natural.
In summary, various tools are used to check diamond quality, including magnification, electrical conductivity, spectroscopy, microscopy, luminescence, DiamondSure, DiamondView, and CVD diamond testing machines. These tools help identify imperfections, differentiate real diamonds from simulants and synthetic ones, and ensure the authenticity of the diamonds.
