These beautiful navy blue and royal blue earrings with strings of gold color. The dangle statement earrings are made with hardboard (an engineered wood) and the design is heat pressed onto the surface. We do not use any vinyl or stickers. The material is engineered with a special glossy surface that accepts the image with vibrant colors. The agate pattern is only on the front side with a plain brown back. These are not actual stone agate, but an agate design pressed onto the surface. Each pair is handmade and packaged in our studio in Illinois!
