Aw, that's really sweet! For our one-year anniversary my boyfriend took me out to a super fancy delicious meal, and he also got a moonstone rock made into a really beautiful necklace for me. I think the fact that he's owned that moonstone since he was 11 years old and then 14 years later decided to give it to me so I could wear around my neck makes it more amazing than any other piece of jewelry I could ever own. Except maybe a wedding ring? haha.
