EDITORS'NOTES Piaget's 'Possession' ring is defined by its revolving center band. It's been crafted in France from 18-karat white gold and illuminated by a single brilliant-cut diamond and 46 blue sapphires that shimmer as they move around your finger. We think it makes a beautiful engagement ring or anniversary gift.
