"Charms can be used for a variety of effects, depending on the charm. A key or lock charm can be used with chain to give a small steampunk effect. These two charms can also be used together for Valentine's Day jewelry, especially withth a heartshaped lock: "this is the key to my heart." The key charm is a cool addition to a smaller stone pendant as the "dangle" at the bottom, which also gives a small steampunk effect."
