These enamel earrings are made by Krista, using powdered glass on a solid copper base and a torch. Each color or element is a separate firing. The backs are black. No two are ever exactly the same. That's the cool thing about enamel, you never know exactly how it is going to turn out! Please take a close look at the photos-I took several for you. While my inner perfectionist says one is not exactly the same as the other one, my inner realist says duplication is impossible with such an art as enamel. I must remind myself that each piece is like a stone, with it's own personality. These cute earrings come in your choice of earwires (use dropdown to choose), or as shown as the default. They measure about 16mm wide by about 22mm high. The earrings you see in the photos are the actual earrings you will receive. Stoppers included.
