Some people like to wear body jewelry that is made of organic materials, such as bone, mother of pearl and even wood. This can be used in tusks to make them look more like real ones. Also organic materials are very popular within some subcultures. Of course it can look very nice but one should remember that organic materials are more likely to cause an allergy and to get infected. Therefore they have to be worn with extreme care and in no way in an unhealed piercing.
