Because when the jade bracelet is broken, there will be some tiny fragments (or small pieces). I wonder if they were collected together. If they are not collected together, there will be some pits after bonding, which will affect the bonding strength on the one hand and the appearance on the other. Cracks are still visible after bonding.
Another way is to ask the master to wrap the connection with gold or silver at the broken place, which is definitely better than gluing and can block the crack. However, the cost is not just gluing.
Whether glued or inlaid with gold and silver, bracelets will always be damaged (disabled), which requires full psychological preparation. As the saying goes, "second time around" is the same with jade bracelets.
It is recommended to use inlay method (better than gluing).
