These earrings are traditionally worn by the Fulani women in West Africa.
They are handmade and made of recycled bronze from old car radiators and the silver are silver plated. The bronze is melted down and tapped out while being twisted.
The bronze is hammered till it is nearly paper thin, and then twisted to create the intricate look of the earrings.
For a normal clean, nothing beats soap and water! Simply wash in warm water and soap, using a soft cloth to gently rub away any dirt and grime. Make sure to rinse the soap off thoroughly before wiping. Store carefully out of the air.
Using a jewelry cleaning cloth to wipe after wearing will minimize tarnish.
