I won the first prize in the supermarket and bought a jade pendant at the cost price of 10%, which is probably a marketing tool of the merchant, but I am not sure whether the pendant is genuine or not.

In order to ensure that the jade pendant you bought is genuine, you can identify it according to the following points:

1. Observation color: The color of natural jadeite is usually uneven and will change with the change of light and angle. If the color of the pendant is very bright and single, or the color will not change with the change of light and angle, it may be fake.

2. Feel texture: The texture of natural jadeite is usually delicate and has a smooth feeling. If the pendant is rough in texture and feels unsmooth, it may be fake.

3. Observe the luster: The luster of natural jadeite is usually soft and not too dazzling. If the luster of the pendant is too strong or too dazzling, it may be fake.

4. Hardness test: The hardness of natural jadeite is relatively high. Scraping the surface with a knife or glass will not leave traces. If the pendant is low in hardness and easy to leave traces, it may be fake.

5. Look at the certificate: If you buy a regular brand jade pendant, you will usually have a certificate. The certificate will have detailed information about the pendant, including color, weight, size, identification results, etc. If these details are not on the certificate, or the information is inconsistent with the pendant itself, it may be fake.

I suggest that you choose regular brands and businesses when buying jade pendants to avoid being deceived. At the same time, if you have any questions about the jade pendant you bought, you can go to the local jewelry appraisal agency for appraisal.
