A Personalized Necklace with Name and Birthstone makes a really special gift idea. Each personalized gold pendant can be engraved with a name up to nine characters and is flush set with a birthstone of your choice. The backside of the pendant can be optionally engraved with a message or date up to eight characters and the bottom of the gemstone is visible as well. This pendant comes in two versions with one that is 14.29 mm (pictured) while the other is 19.05 mm. Every pendant can come with a cable chain if you so choose and can be combined with other gold disc pendants to create a charm necklace.
