Inlaid in brass with a sterling silver post these earrings are hand carved from horn. The salvaged horn used to hand-carve these earrings comes from a domesticated water buffalo used for cultivation and food. To minimize waste, they are respectfully utilized for this form of art and income. The black colored horn has a vibrant polished shine, is light in weight and very durable. Due to the natural characteristics of the material slight variations in color may occur. The 18ga sterling silver posts fit standard sized pierced ears and will come with a pair of earring backings.
