The center bead is made from Ancient Roman Glass Fragments. These beads will vary slightly since each is a one of a kind. We loved using these as the feature bead because they come in all the shades of water. This one has 10mm amazonite beads with 6mm aquamarine accent beads. Stretch bracelet. Perfect for the person who loves the water! Comes in a gift bag with our Live by Water logo hand stamped on it and a card describing the bracelet. Handmade by us! Comes in 2 sizes 7.0" and 7.5" If you need another size please contact us.
