Color: Purple-leaning blue Decoration: Zirconia Material: Silver 925 Thickness: Approximately 8mm This is a pendant head with a swinging bail. The closer the color is to purple-blue, the more valuable it is. The meaning of lapis lazuli is to bring the best of luck in life, to avoid danger, and to give the power of correct judgment. There is a slight indentation on the back, but it was there from when I bought it. Please make your final decision based on the images. Also, returns are not accepted for discounted items.
