(KGT 150):  […] the old practice of identifying one's position within a military unit - for example, one's assignment on a ship - by means of a symbol hung on a chain worn around the neck.

(KGT 205):  For instance, the jInaq, an amulet given to a Klingon girl to symbolize her coming of age, may be pronounced correctly or else "Federationized" to sound something like "gin knack," but there is no word *jinak* or the like in Federation Standard.  [Necklace seen in TNG "Birthright II".]

TREK TRIVIA:

(ST Encycl. 269):  The leader of Troyius gave Elaan, the Dohlman of Elas, a necklace of radans as a wedding present in 2268.  Chemically, radans were raw dilithium crystals, and made Troyius a planet of great strategic significance.  Elaan's necklace served as a source of emergency crystals for the Starship Enterprise when that ship was under attack by a Klingon vessel that ironically sought to guarantee a supply of radans from Troyius. (TOS "Elaan of Troyius")
