1. Elephant Ivory. This category includes ivory from both Indian and African elephants, as well as ivory from mammoths and mastodon. The tusks, or upper incisors, of these animals are used. They can have a cross section of up to 20cm (8), and be up to 2.5m (almost 3 yards) long.nlike human teeth, elephant tusks do not have an enamel coating. They do have a cementum layer, however; ivory dealers refer to this as the bark or the rind. Occasionally this layer is retained on a piece of worked ivory. One-third to one-half of an elephant tusk is hollow.
