So either Rob decided to intentionally put a different pin top on this penannular as a less expensive, simpler option or he mixed up the patterns when putting this together. We'll never tell! Either way this is a unique opportunity to own a modified penannular.
This is the Plume Thistle Penannular in sterling with 14kt Rose gold heads and pin top. It measures about 1 1/2 inches by 1 3/4 inches.
