Collectable, stackable, meaningful—our fan-fave Aura Birthstones have taken new shape. Add an extra bead to your Birthstone Bead Necklace (available in solid gold or sterling silver and vermeil) or elevate one of your other everyday favorites with an extra sparkle of meaning. Each subtle birthstone bead was thoughtfully chosen to work harmoniously with one another (and fit on most of our chains)! Important notes: Expect natural variances in color across pieces—no two gemstones are alike, and may not mirror the photos exactly. Our pearl & iridescent opal beads are ever-so-slightly smaller than the rest (we're talking 1mm!) but still stack together beautifully.
