Very bright, works well with either silver Pandora or leather braid Pandora. If using on a Silver Pandora, you will need a little silicone ring on the bracelet if not placing on one of the two silver bulges. Otherwise, this will be a sliding bead instead of a stopper. If you use this on a leather braid Pandora, it fits the braid perfectly as a stopper, you don't need to use a filler to have this function as a stopper. I think this stopper works better on the leather braid Pandoras than the Pandora stoppers - no need for a rubber or silicone filler. Very happy with the quality and service I received from Beads Hunter.
