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