As a real MCM fan, these earrings are perfect....with the right MCM color and the split atom shape. They are signed on the clip. Sarah Covington is a popular designer, and they are comfortable to wear. If you do not know how to adjust them, a jeweler can help. Very Mad Men, I can just imagine one of the gals from this show wearing these. I know the normal atom splitting symbol has another ring, but I am sure that was the inspiration behind these. A bit of color has worn off one of the beads, but a touch of nail polish or hobby paint, can easily restore. I dig the brutalist texture, too. No corrosion on these. They measure an inch across. The necklace shown is a trifle greener than the stones on the earrings. Great gift!

This item is sold from a vintage boutique in Las Vegas, Nevada.
