A bit of help?

Hey! My German teacher is selling conversation hearts that she got from Germany. I plan on picking up a few boxes, but I wanted to make one heart into a pendant. Can any of you recommend a coating that'll preserve it and make it shiny without messing up the wording? I thought it'd be cool to have a conversation heart necklace that says sweetheart in German. ^_^
