My husband bought me this necklace for our anniversary. The sales lady convinced him to buy it and I don't know if I like it! My husband doesn't really have a problem with me exchanging it for something I like better but I am new to Tiffany and have no idea what is classic, nice, etc. Any suggestions? I am 40 and I just thought this particular necklace seemed a bit young, but I'm not the expert. What do you guys think? Should I keep it or exchange it? If I exchange it, what should I look at? Thank you!
