Gift for a graduating Parish Nurse?

My DON has been taking classes in Parish nursing, which she has wanted to do for so long, and I finally convienced her to do so! She is going to be so awesome! Nurse with 60 years of experience, and would really just like to settle down helping her parish . I am so encouraged by her, she is my mentor, and I really want to give her a very loving gift for congratulations!

Alas, she is my boss...so I have to be a bit careful about gifts. At my facility we have all known eachother for quite some time, and I know a gift for congratulations would be appropriate, but I still don't want to get something huge...would look like I am kissing up...

She wears matching pins with earrings, and I found a gorgeous white porcelain pen with the cross and a lovely flower intertwined and blooming happily across the center. It is from a company called Pure Grace, and it is called HOPE. I think it is delicate and small and speaks largely of my hopes for her!

What do you think? Or any other suggestions? (she is of the Catholic denomination).
