I am using these spacers in a necklace of leopard jasper. The pattern in each bead is complex, and I want to highlight this natural beauty, so these simply shaped pewter beads work very well for me. They highlight the beauty in the beads, whereas a complex spacer might detract. One note: they really are silver-plated, so they tarnish. On the other hand, they really are pewter, too, so if the silver wears off they will still be a beautiful silver color.
