I love the pendant jewelry. I have another one also and I love the incredibly detailed art work.
The Silver Reversible Circular Pendants have Spirit's artwork on both sides, encased in resin. The large pendant measures 1-1/4" wide by 1-5/8" high (including the stainless steel jump ring) x 1/8" thick. The medium pendant measures 7/8" wide by 1-1/4" high. The small pendant measures 5/8" wide by 3/4" high. The CPXS may not have the full artwork and saying on the back, as it is a half in in size.
