What’s Katara’s Necklace Made From?
I propose mother of pearl or abalone shell.
Mother of pearl and abalone shell are both composed of nacre, basically layers upon layers of calcium carbonate stuck together with a protein called conchiolin. This gives rise to a crystalline structure that is iridescent, lustrous, incredibly strong, and fracture resistant.
The color varies based on the species of molluscs, it does come in blue/silver hues. Nacre accepts intricate carved designs and is a resource the Northern Watertribe could theoretically have access to, given the quirky fauna populating Avatar-verse.
Yue’s necklace and hair ornaments, and Kya II’s necklace could also be made from shell. I think in particular, recreating Kya’s necklace would be easy since there’s many options for crescent moon pendants. Cosplayers take note?
