What must I do to absolve myself and my father after I wore golden earrings that my father found in the market while he is still alive?

If the father took the earrings with the intention of possessing and benefiting from them, he committed a sin, and he is obligated to guarantee them to their owner. He does not acquire ownership of them, even if they are publicized for a year, because the intention accompanying the taking is treachery.

If a year passes for a lost item (Luqata) without its owner being known, it should be given as charity on their behalf. The benefit derived from the earrings is also guaranteed, for their use necessitates guaranteeing a rent equivalent to their like.

The fact that the father gifted the earrings to the questioner when she was young does not change the ruling.

To clear her conscience and that of her father, the questioner must give the value of the earrings as charity on behalf of their owner, and estimate the rent for their use throughout the period and also give it as charity on behalf of the owner. If she is unable, she should give whatever she can afford, while frequently seeking forgiveness.
