I made these 2 necklaces using tarnish resistant 18k gold plated brass dot chain with 18k gold plated connecting rings. They have extenders making them adjustable from 19 1/2" to 22" in length. The pendants are organically shape quartz slices wrapped in gold leaf and hang from a 18k gold plated bail. YOUR CHOICES OF PENDANT ARE: #1- Rose Red #2- Yellow * Your purchase will arrive in pretty packaging
