If you want to get back together with your ex-girlfriend:
It doesn't matter what gift you give her. What matters is whether you still have a heart of love for her. If you really cherish this hard-earned love, why would lovers hurt each other? If you love her, take the initiative to call her again. Have a good talk with her, make her a special gift, something that belongs to you, string your memories into "beads" and send them to her, and tell her that you love her very much. I think she will be happy. I hope your love can last.
If you can also give a gift out of politeness:
The first choice of gift should still be a jewelry necklace. For necklaces, it is recommended to have a very popular personalized necklace-name necklace, which is a specially made exclusive sterling silver necklace that can be engraved with words, which can definitely achieve the effect you need. You can also give her some things she often uses, such as mobile phones and makeup mirrors. The recommended makeup mirrors should also be personalized, such as engraving on the mirror.
