Vintage Sterling Silver abstract design ring unique unusual signed

An interestingly shaped vintage ring. Even though the strange shape, it is very comfortable to wear. The width is 3mm, and the size is between 7 and 8. These measurements are approximate. It weighs 1.9 grams. This is a preowned older ring so it shows signs of wear. Some small scratches from every day use and some tarnish. This ring is stamped sterling but I've also tested it. Also stamped ESPO. Let me know if you have any questions.
