The Sterling silver necklace is only standpoint 925 now it looks like a Tiffany piece but I can’t sell it as such because I can’t find any markings other than stamp 925. It is a very very old piece. It really is. I’ve had it for over 25 years but there’s no markings no tags no nothing with it so I can’t sell it as a Tiffany piece there’s 24.grams of work silver. Photograph and pull it up for search. It keeps showing up as a Tiffany, but I can’t sell it as such because I can’t find any markings.
