Red Tiger Eye Necklace

A necklace of 19 rich red beads, given one year during the annual festival of Alphcon to all who attended the festival or bought anything at it. No one knows why the name is given. There have never been Red Tigers in Ur, or, for that matter, Tigers with Red Eyes. So not only were no tigers harmed in the making of this necklace, no tigers existed to be harmed in the first place. Also: what are tigers?
