Hello, most of them are true, but the price of this kind of fair is still relatively high, but be careful.
Yes, jade is real. Emerald is a precious gem, which consists of beryl and jade. It has extremely high hardness and can resist external damage. Emerald is a very precious gem, with delicate texture, soft color, dark green and sometimes light blue.
Jade a beaded necklace, the authenticity of things is beyond doubt, but the value is low, the actual price is several hundred, and the maximum is not more than 500. The purchase of scenic spots will be sold at a higher price. I hope it is not too expensive.
