Promised?

Mt boyfriend has a huge surprise for me on Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>. He has asked what my ring size is what my favorite stone is and said that when it comes time for the surprise he is going to be serious about it. . . I need some other opinions do you think he is getting me a promise ring or more or am I just making a big deal out of nothing?
