Offering for sale a lovely vintage heart charm, it is silver and I believe it to be sterling, but it is not marked. it came on a necklace of over forty sterling marked hearts I bought 20 years ago from a local antiques dealer, which would indicate it be be of same content, but due to being not marked. it is for sale for the decorative value, which is just wonderful ! It is of ornate repousse, embossed designs, and double design, on both sides. It measures 5/8" long, and is in very good condition. I have not polished it in quite a while, as i like the old patina of silver, but it could be more shiny if one desired. ON the puffiness scale, it is moderately puffy.
