Real Cottonwood leaves are collected and dried to remove all the moisture. The Cottonwood leaves are then given a thick Silver coating and turned into beautiful Real Cottonwood Leaf Earrings. The earrings have fish hook style backs with a brass base metal and then are finished in silver. The fish hook backs do not contain nickel and are hypoallergenic. The dimensions are approximate as each pair of cottonwood leaves are real, unique and will be slightly different.
