1, jadeite identification refers to the identification of jadeite products, which can generally be divided into two aspects: instrument detection and manual identification. In instrument testing, the structural crystal is usually tested by polarizer and the refractive index is tested by refractometer.

2, the identification method of water → drop a drop of water on jade, such as dewdrop that does not spread for a long time; The water droplets disappear quickly, which is a fake. 2 Touch by hand → Real jade will feel cold and lubricated if touched by hand. Inspection method → Put jade in bright places such as sunshine and light. If the color is clear and the green is evenly distributed, it is a real jade.

3. Look at the inspection agency. The state has strict requirements on the qualification of quality appraisal institutions of jewelry and Hetian jade, and only the appraisal certificate issued by the recognized appraisal institutions is valid. Formal hetian jade appraisal certificate will generally have one of the words CMA, CAL and cncal. If there are none of the three, it is a false certificate.

4. Touch it with your hand and see if you can find it. If you look at the light with a magnifying glass, there must be large and small bubbles inside.

5. One: Magnifier Zircon is very similar to diamond and is the best substitute for diamond. The identification method is that zircon has polarization and large birefringence. Observing the processed zircon prism surface with a magnifying glass of 10 times, it can be seen that the bottom edge line has obvious ghost, but the diamond has no ghost phenomenon.

6. The simplest identification method of jadeite is: luster: after being soaked in strong acid and alkali, jadeite has loose structure, and there are dissolved pits on the surface before it is filled, which makes it spread and its luster weaken.
