This video talks about the process to register your personal Gold Jewelry with the Customs Bureau and Protection (CBP) before traveling out of USA. This talks about how to fill CBP Form 4455. Note that this process is relevant to US and not to other countries.

Some CBP offices might ask for evidence to prove that you own your personal jewelry. So, take some kind of evidence such as purchase receipts (if you purchased them in US) or Jewelry appraisal or Jewelry insurance policy or pictures wearing those Jewelry etc.
