Okay, kiddo, so a necklace ring is a little circle that you can put on a necklace. It's like a tiny hoop that you can use to attach other things to your necklace. It's kind of like a keychain but for your necklace instead of your keys. You can use it to add charms or pendants to your necklace or to connect different pieces of your necklaces together. It's a small but important part of making your necklace look pretty and unique.
