The bone and horn used to hand-carve these organic earrings comes from a domesticated water buffalo used for cultivation and food. To minimize waste, they are respectfully used for this form of art and income. The various pigmentation on these tribal earrings are the natural color tones found on the bone & horn, except for those which are clearly inlayed. Although your ear appears to be gauged, these split expanders fit like regular earrings. When wearing these horn & bone earrings, be sure to push the sterling silver post all the way into the second half of the earring, at a slight angle.
