1837 925 Silver, Tiffany & Co. This is a Tiffany & Co. ring! Purchased quite a while ago, it has a fair amount of scratches, but it has been cleaned and has little blackening. I looked for the box, but couldn't find it. The size is about a size 12! It is also listed elsewhere, so it may be sold out. Also, as it is a used item, please refrain from purchasing if you are sensitive to such things.
