It is a tradition in my family to present our daughters with jewelry as they turn that magic 40th year. I'm sure she'll be as thrilled with this as I am. For such a large stone, the size of the piece, overall, is perfect. Not flashy, just beautiful.
This necklace looks just as good in person. My only complaint is that the jump ring (the ring that you attach to the clasp) is very small, so putting it on yourself may be a bit tricky.
