I texture my metals in various ways and these earrings are patinated. This patination is a simple chemical process using non toxic ingredients and can take up to 2 weeks to create the right finish. I create a piece of metal then cut into various shapes. These earrings have been cut and filed into a diamond shape and I use gold hooks to finish them off. The patination is permanent. I have other earrings different shapes in this series and some have semi precious stones added. Please contact the artist for further information.
