2. Identify by hardness. Real jadeite has a high hardness. We can scratch or scrape the surface of jade with sharp nails or knives. If it is real jade, the surface of jade will feel very slippery and will not leave any scratches. False jadeite will scratch the surface after being scratched by hard objects, leaving obvious scratches on the surface.

3, the surface should be smooth, without all kinds of processing marks, casting jewelry without cracks and obvious defects. A bracelet should have a straight axis. The chain bodies of bracelets and necklaces do not rotate vertically, and the size of buckles matches the chain bodies. The needle length of pin earrings should be consistent, the chuck should be stable and so on.

4. If conditions permit (raw materials or semi-finished products), use timely carving. If it is "water foam", it is easy to paddle. If it is jade, it is difficult to paddle, and the feel can be distinguished.
