No.442
A Fijian Tabua aka a sperm whale tooth on a hand made coconut fibre sinnet cord used as a necklace. The Tabua is attached by a hole made at the tip and base.
 
This Tabua has a short cord and I can't make out any scrimshaw on the tooth which measures 16cm x 6.5cm. The tip is chipped and the cord is worn just past the middle (see images)
 
In Fiji beautifully polished whale teeth are known as “tabua.” They hold a potent spiritual value. They are considered sacred, hence the name “tabu-a” [tabu = sacred]. Traditionally they come with a braided sinnet cord attached at tip and butt.
Tabua were a social necessity. They were ceremonially presented on all formal occasions. Their acceptance by a chief bound him morally and spiritually to another party or a desired course of action. This usage continues today.
