This is a necklace I received as a gift. It features a beautiful green color, but I don't know much about it, so I'm not sure what kind it is... I'm selling it to someone who knows more about it or someone who likes this kind of necklace. It's new and unused, but there are some marks on the box where the sticker was removed. Please be aware of this. The necklace itself is 80cm long. It's a bit long.
