Piaget's iconic 'Possession' collection first found fame in the '90s. Made in France by master craftsmen, this necklace is strung with a 15.72-carat red carnelian pendant that's said to protect against negative energy. It's centered by a rotating 18-karat rose gold band - symbolic of the choices every woman makes for herself as she maps out her own destiny - encrusted with a single 0.016-carat brilliant-cut diamond.
