Here's a couple of pics of the ring. The number inside appears to read 230 but not sure, I did test it and it holds it's own with the 10k n 14k acid but dissolves with the 18k. Suspect Mexican gold, 95% of the bathers are hispanic. What do you guys think? Also found a SS Fossil watch and bunch of clad and 3 junk rings, watch crystal has water droplets inside although it says on the back that it's resistant to 30 meters/100 feet. Thanks for looking. HH
