Heart Necklace Chain: Approximately 40cm Please refer to the photos for the shape and size of the pendant. There are no markings and the stones are unknown, but it sparkles beautifully. I received this as a gift and only tried it on. I believe there are no noticeable scratches, but it is not new, so please understand that there may be minor imperfections. It will be sent via Mercari delivery in simple packaging. Thank you.
