Traveling with jewelry

My father wanted to buy these jewelry for my mother for their anniversary but my parents both live in the Caribbean country and I live in the US so I bought the jewelry to send the jewelry trough a family friend to my father now my only problem is on how to package the items so that they arrive safely to their destination because it would be terrible if something happened and the total was about $200. Anyone has any idea on how I should package the jewelry to give to the family friend? should I even tell the person that they are jewelry any ideas I would help
