Vintage 14K. Gold, Solitaire Studs, With 3mm, 1/8th Karat, each.                                                            Full Cut Diamonds. I got these for a gift about 35 years ago. They are not marked 14K Gold, as the studs have been changed out, and the marking was on it.  I did have my jeweler examined them, he told me they are VS1 -2 they are clear full cut Diamonds.
