1. You can go to the National Jewelry and Jade Quality Supervision and Inspection Center to identify jadeite and Hetian jade. The National Jewelry and Jade Quality Supervision and Inspection Center is a national professional quality inspection institution authorized by the relevant competent departments of the state according to law, and it is the authoritative institution for jewelry and jade testing in China.

2. Valuation factor: water head, that is, transparency. The more transparent the jadeite, the better. There are many terms in the industry to describe the transparency of an emerald, such as glass seed, ice seed, wax seed and so on. Texture. Texture is easily confused with seed head, because many times jadeite with good texture is transparent, but texture refers to the structure of jadeite, that is, whether the crystals of jadeite are uniform, tightly combined and loose. Color. The color is emerald, not green. But I have personal hobbies, some like yellow, some like purple, so I will only say green here. There is a four-word formula for evaluating the green color of jadeite: thick, positive, clear and even.
