A simple open loop of braided copper wire. Post earrings.
Braided Copper Half Loop
NOTE: I've made multiple pairs of these in-demand, versatile earrings that can be coordinated with any copper pendant. Each pair is basically the same with very minor variations. So, the ones in the photo may not be the exact ones you will get, but they'll be almost the same.
I used pure copper wire, oxidized it to achieve a timeless "antiqued" look, polished it to bring out the copper highlights, and then sealed it to capture its patina and prevent further darkening. No further polishing will ever be needed. Protect from scratches and bumps against hard surfaces or other jewelry. Push and pull posts gently, but firmly into and out of earring backs.
