I is the inside part of a long shell ground down by hand. (It took Tegumai three months to grind it down.)
J is a fish hook in mother-of-pearl.
L is the broken spear in silver. (K ought to follow J of course, but the necklace was broken once and they mended it wrong.)
K is a thin slice of bone scratched and rubbed in black.
M is on a pale gray shell.
N is a piece of what is called porphyry with a nose scratched on it. (Tegumai spent five months polishing this stone.)
O is a piece of oyster-shell with a hole in the middle.
P and Q are missing. They were lost, a long time ago, in a great war, and the tribe mended the necklace with the dried rattles of a rattlesnake, but no one ever found P and Q. That is how the saying began, 'You must mind your P's. and Q's.'
R is, of course, just a shark's tooth.
