Diamonds can be identified by checking the hardness of the diamond, checking the thermal conductivity of the diamond, checking the texture of the reflected light of the diamond, and checking the color of the reflected light of the diamond.
1. Test the hardness of the diamond
Items: Diamonds & knives
Inspection process: Pick up the knife and test the diamond for scratches
Inspection criteria: If there is no knife scratch left on the diamond, the diamond is a real diamond; If there is a knife scratch on the diamond, then the diamond is not a real diamond.
2. Test the thermal conductivity of diamonds
Preparation: Diamond & Glass
Testing process: The diamond and glass are placed in a common environment, and two people breathe on both items at the same time, waiting for a few seconds
Test criteria: If the water vapor on the diamond dissipates faster than the water vapor on the glass, then it proves that the diamond is a real diamond; If the water vapor on the diamond dissipates more slowly than the water vapor on the glass, it proves that it is not a real diamond ring.
3. Check the reflected light texture of the diamond
Items: Magnifying glass & diamonds
Test procedure: Use a magnifying glass to observe the reflected light on the waist of the diamond
Inspection criteria: If the reflected light on the waist of the diamond shows a matte shape, and also accompanied by dazzling shiny characteristics, it proves that the diamond is a real diamond; Otherwise, it's a fake diamond.
4, check the diamond reflected light color
Preparation: Zirconia imitation & Diamond
Test process: Rotate the two objects at the same time and observe the color of the reflected light
Inspection standard: The light reflected by the artificial zirconia imitation when rotating is colorful, is colorful; The color of the light reflected by the diamond when it is turned is only a faint yellow and blue.
