Modern chic ear studs were handcrafted out of copper sheet scraps I had in my studio. After studs were designed and assembled through forming, soldering and sanding a light blue/aqua patina, colorful surface oxidation, was brushed onto the surface. Color is sealed with sprayed finish to ensure long lasting color, to ensure protection please keep them out of water. Please note that the color looks more intense in the photographs listed due to the light set up. The ear wire is sterling silver. Perfect pair of earrings to coordinate with your wardrobe.
