Checking the quality of a diamond involves several tools and techniques that help in identifying its authenticity, imperfections, and overall value.
5 Essential Methods Explained
1. Magnification
Magnification is a crucial tool for checking diamond quality. It allows for a thorough inspection of the diamond, helping to identify blemishes and anomalies such as inclusions, feathered wisps, or scratches on the diamond's surface.
2. Electrical Conductivity
Electrical conductivity is another important tool, particularly in differentiating real diamonds from moissanite. A tester that utilizes electrical conductivity can help determine diamond simulants from genuine diamonds more accurately.
3. Spectroscopy and Microscopy
Laboratories use various techniques and instruments to determine a diamond's origin and quality. Spectroscopy and microscopy are among these tools, helping to identify synthetic diamonds and differentiate them from natural ones based on their color, production method, and imperfections.
4. Luminescence Under Shortwave Ultraviolet Light
Luminescence under shortwave ultraviolet light is another method used to check diamond quality. It helps in identifying synthetic diamonds and differentiating them from natural ones.
5. CVD Diamond Testing Machines
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.
