Nautilus-Design [Player] Armor Trim (for Players)

This isn't armor trims for nautilus armor, this is an armor trim for player armor, that makes player armor look like the stripes on a nautilus' shell.

They could either be horizontal(ish) stripes, or a spiral symbol. Or maybe the helmet has horizontal(ish) stripes, but the chestplate has a big spiral symbol. Personally, I think the helmet should resemble the nautilus shell the most, since it's the one that matches the shape most closely.

I think the armor trim material could be prismarine, possibly dark prismarine, with a spiral or three striped lines on it.
