Medal Pendant Catholic

I need advice on what I am getting my cousin for her Catholic Conformation?

I was a nominee for her sponser. I am religious, and i wanted to give her a Virgin Mary pendant. Her family heard a rumor that I lost my virginity at 16. It is true. I don't want something like that to happen to her at a young age hence the Virgin Mary medal. Would that be appropriate?

Yes, of course that would be appropriate.
