I have seen the photos you posted. These three models are all Jade A goods, and there is no doubt that they are genuine.

The testing organization is a national testing qualification, but the certificate can prove the authenticity and does not represent the value.

The above three models are all products with a 10% discount.

You can check my answer record. Basically, this kind of gold inlaid jade 925 silver inlaid jewelry is a common product with discount promotion.

In addition, articles in Baidu Space also have related words.

Jin Xiangyu's evaluation is as follows.

Shopping malls are mostly sold at a discount by lottery, with ordinary jadeite materials with thin gold in the middle (generally, one gram of gold can be made into pure gold paper of about 0.5 square meters with a thickness of 0. 12um).

In the case of no cracking, the actual price is within 300.

925 silver inlays are generally items within 100 yuan, and the market price ranges from 200 to 400.

Can be judged as genuine, but the price is a little small and a little expensive.

If you have any questions, just ask.

I hope the answer can help you.
