The pearls in a 1 lb. bag measure 9/16" in diameter which is just over .5". That's a pretty good sized treasure! Easy to use, just place in the bottom of a vase and these amazing gems are ready to support a flameless LED candle or to secure your floral display. They also look fabulous in a dish surrounding a candle. We have lots of sizes so whatever your project calls for, we've got you covered! Create contrast by mixing up the sizes or create a colorful display by tossing in our crystal or acrylic pendants! These beads do not have a hole in them.
