Reflected by light and shadow: diamond reflects weak light, zircon reflects colorful light. Observation of surface water droplets: diamond surface water droplets do not disperse for a long time, zircon surface water droplets quickly spread. Distinguish transmission lines: diamond pavilion surface can not transmission lines, zircon will see scattered lines. Distinguish triangle star: diamond triangle star face sharp, zircon triangle star face round blunt.
1. Reflected by light and shadow
When the diamond and zircon are placed in the sun at the same Angle, the diamond reflects a weak light, and the zircon reflects a scattered colorful light. Diamond light reflects weak and concentrated yellow and blue light, while zircon reflects scattered sheets of colorful light.
2. Observe the surface water droplets
After cleaning the diamond and zircon, put water droplets on the countertop respectively. If the water droplets can remain on the table for a long time, it is a diamond; But if the drops spread quickly, it's zircon.
3. Distinguish transmission lines
Put the diamond and the zircon in the same straight line, looking down, the diamond will not see the line, the zircon will see the spread of the line. Diamond pavilion surface can not transmit lines, and zircon pavilion surface can transmit lines.
4. Identify triangular stars
If the diamond and zircon are placed in the same position, it can be found that the triangular star face of the diamond after cutting is sharp and angular, and the triangular star face of the zircon after cutting is round and blunt.
