This is a necklace made of various sizes of genuine amber. (Please check the size in the photos.) This amber is genuine, as it floats in saturated salt water. Also, amber is light, and this one weighs only 14.5g, so you can wear it without feeling burdened. A large K18 mirror-cut bead is placed in the center. The size is approximately 43.5cm including the clasp. The clasp is a SILVER bean-shaped insert type (new). The case is for photography purposes only.
