What is a fun little technique to give a present to my mom?

My dad and I purchased a charm bracelet from Brighton's yesterday, and today is their anniversary. Do you guys know any smart, slick way to present the present to her--she is absolutely going to love it! I heard of this one guy who made a scavenger hunt for his girlfriend and once she found the last piece, he wrote in little letters 'will you marry me?' inside of it--i find that really cute. But are there also any other ideas that you guys may have? Thank you in advance.
