Lights up (see a second photo). We are a secondhand store. While we do test (unless stated otherwise) items we sell we are in no way experts in all fields, thus the testing we do is limited to basic functionality. There might and probably will be issues or problems that we missed. We sell all jewelry as-is and this means that your piece may need polishing and/or repairs. We try to describe items well, but this does not mean that we list all defects and flaws. Buyers may find ones we missed. The color of the item might not be rendered correctly on photos.
