Send necklaces and bracelets when you are in love, K gold when you have money, and silver jewelry when you have less money.
Send earrings when you break up. Swaying and swaying, there are thousands of customs.
The above is my personal opinion, but it is necessary to give a small creative gift and a big diamond ring when getting married.
Creative jewelry must look good, fragrant jewelry, rotatable jewelry, jewelry with simple design.
