Paula says - "These machine made beads are hand finished by various workmen and women at shops in Gallup, New Mexico. They have a satin finish and are antiqued and then polished in the middle so each bead is dark on the ends and silvery around the center. Very striking!"
like these are great for hanging pendants!
100% solid silver won't tarnish but it is too soft to use for making jewelry - it could easily be scratched, dented and bent. Sterling silver has a small amount of one or more other metals usually copper, added to the silver. To be called sterling silver, the alloy must contain at least 92.5% pure silver. Sterling silver alloy is harder than pure silver but the added metals also can cause discoloration or tarnish.
