There are often fractures and cuts in the jade, which are generally not easy to observe, and if you knock it with a metal rod or gently throw the jade on the plate, you can distinguish whether the crack exists or not. The crisper the sound, the better.

There are black spots and flaws in the jade that are not easy to find with the naked eye, as long as you take a photo with a 10x magnifying glass, you can see it at a glance.

There are many people who make a fortune by gambling on jade, and of course there are many people who have lost a lot, and gambling on jade is a high-risk and high-reward industry.
