Ring, gemstone, Sz 7.25, silver tone jewelry

Ring is in good condition and kept in a clean smoke free home. Ring is marked inside KCR 7. Not sure who the maker /brand is. The larger stone tested as a gemstone and the smaller did not move the presidium II needle. Presidium II only tests several stones so I can only say the larger one is a gemstone. The other does not look like a gemstone. Ring did not test silver. It’s just a silver tone ring. Received in a vintage box. #ring #gemstone #silver-tone #jewelry #KCR
