The 'engagement' rings are D20 spinner rings because we both share a passion for Dungeons & Dragons and tabletop gaming.
Our wedding bands are Legend of Zelda song rings! Meaning they are an ocarina song from the LoZ: Ocarina of Time, in particular the Song of Storms. The inside of mine is engraved 'Wisdom', his is 'Courage', I will let you figure that one out.
Fun fact: J's ring diameter is three inches!
