This heart and chain would make a terrific gift for a teen girl or a young woman. The set is marked 925 sterling and has a gold overlay., The heart has 5 small emeralds and some white work on the other side to make an interesting pattern. I don;t think there are even tiny diamonds but it does look like it does. The chain is also overlaid with gold, and is 19 inches. This will come in a pendant box ready to give as a gift. For you from the High Plains of Kansas!
