This is a custom made Sterling Silver ring with the letter of your choice Hand Engraved on it by me. It measures 3/4 inches by 1/2, 20mm. I will make it in your size. If interested I will show you the fonts I use for that ring or if you like a different font better I will use it. I can make this ring in other metals as well. It is not light weight and will last a long time.
