Sterling Silver Etched Band Ring Size 8

Vintage sterling silver band with etching that includes plus signs and round "waves". I'm not sure what the artist was intending with this piece, but it feels like a message to see the positive among the ups and downs of life. Or I could be reading wayyy too much into it, lol. It's stamped inside with a 925 for sterling silver a copyright symbol and a group of letters that look like PSOL to me. Size 8
