Circle-type logo on earrings

[connollydesign]

Hello. Could someone help, please? The mark is corroded and hard to see. It's even worse in the photo. I tried to draw it, but it's probably totally off. Now, looking at it again, there might only be two "legs" coming off the circle. The earrings are about 2.25" high, minus the wire. THANK YOU. shawn
