Made from sterling silver, this necklace features a butterfly pendant with engraved surface details hanging from a thin chain, and a round spring clasp which fastens it together at the center back. A short extension chain at the back (with a small, flat, round pendant hanging from the end) makes the overall fit of the necklace customizable. Delicate and feminine, this necklace will add a subtle, graceful touch to any outfit, whether casual or formal. Also check out Heart Pendant Necklace Silver.
