My chain broke and should be repaired

My bracelet is broken.

I have a silver ring and would have it gold plated, is that possible and how expensive would it be?

Hi, Please repair the chain lock.

Hi, I only want to have a small part of a silver ring gilded with pearl. Only the area around the pearl should be gold-plated. The rest should remain silver.

The chain is too long for me and I would like it shorter
