I received this item from someone, and had it appraised at a pawn shop. They said it was either a Tiffany Open Heart or something similar. I couldn't find any hallmarks, so I assume it's a fake. I don't know the market price, so I'll list it for 5000 yen for now. I'm open to price negotiations, and will consider reasonable offers. Also, I'm sorry, but I can't hold items or create reserved listings. Thank you for your understanding.
