Post-set diamond means that the surface of the object is not set with diamond when it leaves the factory, but later the object is upgraded by vendors or individuals, and the diamond is set on the object by the inlay master.
Post-diamond setting is a common processing technology in the jewelry market, but in some brand jewelry, the post-diamond setting jewelry will not be recognized by the brand because the appearance of the object has been changed, and may even be considered as a fake.
When you want to distinguish between a set diamond and an original diamond, you can touch whether the height of the diamond is uniform. If you touch the diamond-encrusted part of the object with your hand, it means that the diamond on the object is embedded in the back.
