This necklace is made from an image I made out of a photo I took of an Iris flower. The necklace will come with the 18" chain in the photo. The charms total about 4 inches long. The smallest charm is about 1/2 inch across. The largest charm is about 1 inch across. This necklace will be a great addition to your collection. It is hand made and there is not another one like it in the world. Please remember that colors may look slightly different on your computer than they do in real life.
