The salvaged bone 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 white colored bone 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 post fits a standard size piercing, rarely causes irritation, and is a great alternative for people who are sensitive to metallic earrings.
