I sculpt my Eco designs from a material made with recycled water bottles!
The ear-wires are sterling silver, or gold filled. They are colored with powdered pigments, metallic acrylics or lacquer, and finished with gold leaf, silver leaf, or copper leaf. They are super-light, and come in a variety of sizes and a multitude of color combinations.
I carve a groove into the piece itself so they clip closed but there's no visible hook.
