If the diamonds on the ring are stuck with glue, the glue will inevitably fail if worn for a long time, resulting in the phenomenon that the fine diamonds on the ring become loose and fall off. At this time, it can be repaired by re-bonding with special glue. After all, diamond rings have been worn for a long time, and even the best materials will slack off. Therefore, in the process of wearing, you'd better always check whether there is any problem with your diamond ring and whether the inlay is still firm. If there is any problem, it should be sent to a professional luxury maintenance organization immediately.
