This pin is very lovely and very understated. It is sterling silver with marcasites around the outside edge of each star. Marcasites glitter when the light hits them. Unfortunately they do not do this for the camera. When you see this in person it is beautiful. Stars in jewelry are an age old theme. It makes one happy to see stars and this is what you will experience when you wear this pin. It is subtle glamour. Pin is about 2 7/8" across and a little over 1 1/2" wide. It is marked 925 R and in excellent condition with some old patina on the back.
