These pendants are similar in what they are made. Both are solid sterling silver with tiny diamonds. The key pendant has a hallmark for Tara Jewels of an F within a Star. It has two heart shaped rubies and diamonds set in Sterling Silver. It measures 1-3/4" long and weighs 3.1 grams. The circle pendant is made by Marsala and is set with 15 diamonds. It measures 1" diameter and weighs 1.8 grams. Both pendants are in excellent condition with all stones present. The diamonds are not of the best quality; they are accent diamonds added to add some sparkle and shimmer when turned in the light. My photos however do not do these pendants justice. They are bright and beautiful. The Key to my Heart pendant would make a nice gift for someone you love. The circle pendant has a hidden bale, so it slides onto a chain without a jump ring Please view the other pendants and charms I am listing. Additional charms in the same package will ship for FREE.
