Advanced laboratories use high-quality testers that can identify a wide range of diamond alternatives to determine if a stone is a diamond. The most reliable method to test a diamond is to put it under UV light and watch the reaction. Most diamonds emit a blue glow, but not all. Some diamonds do not shine under UV light. Therefore, if the stone is not shining, the results do not necessarily indicate that it is a fake diamond. To be sure in this regard, advanced equipment of a laboratory is needed. Because in order to understand whether a diamond is real, various proven test methods are applied in the laboratory environment and advanced equipment is used.
For example, a thermal conductivity probe (a diamond tester) is used to evaluate the brilliance and cleanliness of a diamond. Gemologists (gemologists) often use a thermal conductivity probe or meter. With this device, the thermal conductivity of the gemstone is determined. Diamonds are effective conductors of heat and quickly dissipate heat if heated. If the gemstone radiates heat more slowly, the diamond is not real.
Gemologists often have a very finely tuned scale to measure small differences in weight. A real diamond weighs less than a fake, but special scales can detect these small differences only by carats. With these scales, high profile weighing of real diamonds is made.
Another test method is to use electrical conductivity. Diamonds conduct electricity better than the strongest fake stones. An electrical tester gives a clear indication of whether the stone is real or not.
The brightness and cleanliness of diamond stones are also determined using a microscope. In a power microscope, stones are examined at 1200 times magnification. At this magnification level, the smallest residues and differences can be detected in diamonds.
X-ray machines are used in laboratories to determine the intrinsic and molecular properties of a stone. This reveals whether the stone has a radiolucent or radiopaque molecular structure. Diamonds are radiolucent, while fakes tend to have more radiopaque properties.
