An incredible desirable old mine diamond set in tested 10kt gold.

It is typical of these rings not be marked a gold content since there was no regulation or standards of the time.

This ring is in overall good condition despite age. The diamond is small but reflective. Very dainty.

Small size can be enlarged with a reputable jeweler.

Standard diamond testing is not always accurate or  reliable due to the way the diamond is  cut but the ring was  tested and taken to a  professional jeweler! It was cleaned at jeweler so many pics show the original patina the later pics show after cleaning

European cut. Unclear on Carat weight(1/16)
