I'm a BIG fan of these lava stone beads! I have made multiple orders of this bead, I make essential oil diffuser bracelets and like the quality a lot. Remember when adding oil to these beads lay at least 3 paper towels down one on top of the other, DO NOT do this on a wooden table! Place ONE drop of oil to each bead, wait until it absorbs before moving the paper towels. Always make sure you are using a skin grade oil! Do not add any kind of oils to your skin it could really hurt your skin. You can't go wrong with this bead. xox
