I would pick a 10 motif YG Mother of Pearl. It was my first (many years ago) and I love it like the day I received it. I added another 10 motif YG MOP a few years later and now I wear it sometimes as a ten and sometimes as a 20 motif. MOP goes with almost everything and it is so beautiful. For those that do not like the clasp showing I always manage a way to hide the 2 clasps or make them less visible.
