"Elk ivory" is not ivory, it's a tooth. There are two teeth in the elks mouth that are easily removed and are called the, "Ivories" by elk hunters. It's not like elephant ivory, or walrus tusks, it's a damn elk tooth, and every year all the legally harvested elk bulls have those two teeth removed by the hunter as trophies, just like saving the antlers and eating the meat, and tanning the hide. There are imitation elk teeth made now days to satisfy the demand created by the mountain man, fur trapper, Indian rein-actors. There is nothing illegal about selling an elk tooth unless you poached the elk, and that's a different story. Elk aren't an endangered species. List the item as "BPOE Jewelry with tooth," or Elk tooth jewelry," because the word "ivory" seems to be what the computer program is keying on.
