This is a beautiful Czech bracelet. There are no markings on it but there is no doubt that it is Czech. The three links with the marbled green pieces are quite spectacular. They look like natural stones but I am quite sure they are glass. In between are two pretty links with a delicate stamped design, a wonderful contrast to the size of the stones. Where there are double ridged links connecting pieces they are silvertone. Where there is one ridged link it is goldtone. Love this unusual and interesting bracelet. It has a very nice, large spring ring clasp and is in excellent condition with a little wear to the metal. Bracelet measures about 7 1/4" and is almost 3/4" wide.
