Van Cleef in action!

To answer your question, I prefer the signature WG. The proportions look best imo, it's all really pretty together. The clover overpowers to me. The YG while lovely and soft, does not fit as nicely with the other two beautiful white pieces. Happy Birthday!
@sleepydoc. thank you for your thoughts! I am leaning towards the WG as well. I initially thought the signatures might be too plain. But the shine factor is so high. And thank you for the kind birthday greeting! I plan to celebrate my 50th Birthday which happens in November all year!
