I've made a final, drastic price reduction of 2,500 yen! ^_^ This is a natural stone necklace with a silver chain. I believe the original price was around 18,000 yen, but I don't remember exactly, sorry. ※It's difficult to see, but I've uploaded photos of the chain and necklace where the hallmarks are, just in case. I only tried it on once after purchasing it, and it's been in storage ever since. I'm putting it up for sale now. I think the chain alone, with its hallmarks, is a good value.
