Jewelry markings

Topic: Other


I have a ring with a stone that looks like a diamond. Inside the ring is a jewelry markings that looks like an arrow and a number next to it. What is it? Does this mean the diamond looking stone is real?

Probably a manufacturer’s stamp. Visit a jeweler or independent appraiser with a thermal conductivity tester, and ask them to test it for free.
