Tiffany & Co. pin in iconic robin’s egg blue and silver. No metal purity stamp, but the blue does look and feel like enamel. No imperfections! Has never been worn! Comes in its original white 100% cotton drawstring pouch as pictured. It originally came with a white outer box, but the box was damaged so I don’t want to sell it. Feel free to ask me any questions! This IS an authentic item from Tiffany that was given as a corporate/PR gift. I don’t think it’s fine jewelry, but it is collectible and gorgeous on.
