This is a lovely soft green color necklace and the camera pick up some different shadings that I could not see with the naked eye. When you look at it it will appear all one shade but you pick it up and look through it you will shades and stripes. It is 20 inches but has a pendant of 3 1/2 would be great to wear with a turtle neck. If you wanted it shorter you can catch the shorter hole with the clasp. As part of the decoration there is some lovely wire work. From Kansas with love!!
