I found a ring and I don’t know if it is real. I looked on the inside of the ring and their was a stamp with pl.The strange thing is that the ring looks gold.Is this a fake or the real mccoy
PL could be the manufacturers stamp. Have you tried the other tests in the article Is it the Real Thing? If you still think you have something, ask your local jeweler to test the ring with a thermal conductivity tester.
