K18 black opal 0.2ct ring
Black opal looks like various colors are playing elegantly. You will have so much fun looking at the different colors that it will be difficult to find the same color again. The arm design with two thin lines looks just like antique jewelry! I think it will give you a deep feeling as if you are feeling the history.
