The diameter is 1.5cm (0.6") and the earrings come with rubber bell stoppers (silver plated butterfly earring stoppers available on request). These handmade earrings will be a perfect gift. The earrings are hand sculpted using high-quality polymer clay. Each little detail is made by hand using a small needle. I have invested many hours of patience, creativity and love are in the making of it. Handcrafted polymer clay cabochon is nestled in a silver plated metal base. Each pair of earrings is unique and unrepeatable as they are not mass-produced. The earrings are very light and comfortable to wear. Please avoid using your perfume directly on the polymer clay jewelry. Be aware that prolonged exposure to water can damage clay items! Also since it is clay try not to drop it as it may crack or break! Please note that real colors may slightly differ from those in the picture due to your monitor settings.
