- For information on the goblin in LBRS, see Bijou.
A bijou is "a small, exquisitely wrought trinket". As of patch 1.11 bijou are only used in A Bijou for Zanza, which can be repeated to gain reputation with the Zandalar Tribe.
Do not just destroy it like any other item (some have made this mistake.) Take it to Yojamba Isle and right-click the bijou when you are standing before the Altar of Zanza.
Each Bijou gives 75 Zandalar Tribe reputation for being destroyed, and the resulting Zandalar Honor Token gives 50.
