My grandma past away and I came across this ring. There are no markings on it so in thinking costume jewlery. how can I find information on it I have been searching the Internet for days.
I agree, take it to the jewelers. They can test the white stones at least to see if they are diamonds and they can test the metal to see if it is gold. You can take a strong magnet to it and see if it sticks. If it does, than it is not gold and is plated. Hopefully it is real.
