This is a vintage sterling silver charm of lovely scripted letters MSE. It measures 7/8" inches in length with the bail ring by 3/4" wide and it tested as sterling silver. There are surface scratches that come with age. It will make a nice addition to any bracelet if these letters are your initials.
Please note that my photographs are highly magnified for ease in viewing details and condition of the item and to point out any flaws or imperfections and sometimes are not visible to the naked eye. Once in a while items photographed look gold in color but they are indeed silver in person.
Thank you for looking!
