Found this silver looking ring in about chest deep saltwater but has no markings. The inside looks like someone took a file to try and make it larger. The tone my excal gave me was mid-low which is the tone I always like to hear. When I first saw it I thought it was white gold but have my doubts. The ring on my left is a 14k gold ring and both rings sounds exactly the same on my excal. On my G2, the 14k comes in at 53, the one I found comes in at 52. The 14k weighs 4.95 grams and the other weighs 5.8 grams, it is a little thicker. Maybe I should have it tested before throwing it with my junk rings? Thanks for looking. John
