Metal Detecting Gold and Silver Carlsbad-Southern California Beach

My metal detecting finds near Oceanside and Carlsbad, beaches in Southern California were fruitful! I have not tested the ring yet, but I believe it is white gold and I know the other ring is sterling silver. It's possible the other ring I believe to be gold was a loop in an earring because it is much too small to fit on my fingers or toes. My wife thinks it is stainless steel. I don't know, but it is pretty shiny.
