What metals and gem stones are associated with the sea, in any culture? I am creating a character for a story, and I am designing a knife. So far I have a Laguiole (French) knife with a stylized flying fish instead of an insect, made of titanium with a mother of pearl handle carved with waves.

If you wish to suggest stones, metals, or woods associated with any of the other elements (fire, air, earth are the ones I am using), go ahead.
