Sm Dragonfly Pendant Charm We hand cast our pendant charms in small batches of 6-8 at a time, insuring the quality of the image and finish. Our necklaces are cast using 100% lead free Britannia pewter. Each necklace is strung on genuine leather cord made in Greece by a family owned operation that has been making leather cord for several generations. The cord simply ties in the back and is approximately 24” in length. Most pendants are approximately 3/4" in diameter.
