Animal products that are not acquired legally are not suitable as a raw material for the manufacture of body jewelry. There are ethical alternatives for some material such as fossilized mammoth , mastodon, or walrus ivory, which is a mineralized material most commonly found in Siberia or Alaska . Every year, large amounts of mammoth ivory are exposed in the permafrost of Siberia. The abundance of mammoth ivory, and the fact that the trade is legal, has dealt a hard blow against the illegal ivory trade . Mammoth ivory can be found in more than the normal white/yellowish colors normal ivory has. This is because minerals in the ground sometimes color the ivory. Unless it is properly cared for, mammoth ivory is prone to cracking caused by changes in temperature and moisture levels.

In the 1960s a Californian psychiatrist and expert in facial expressions, Paul Ekman, (with Sorenson and Friesen - see references ) conducted and published extensive studies with people of various cultures to explore the validity of Darwin's theory - that certain facial expressions and man's ability to recognize them are inborn and universal among people. Ekman's work notably included isolated tribes-people who could not have been influenced by Western media and images, and essentially proved that Darwin was right - ., that the use and recognition of facial expressions to convey certain basic human emotions is part of human evolved nature, genetically inherited, and not dependent on social learning or conditioning.
