Cool teal-green agate banded with ribbons of white and deep navy, each face its own cross-section of the stone, the numerals cut down and pooled with oxidized rust-red. Every glyph is real recessed geometry, sunk into the face so the red holds its line against the bright strata. The full polyhedral set, plus a d2 and a d16, all polished to match. A cool banded mineral with a tide line in every face.

Tidestone is pulled from the shelves where the sea has worked the rock for an age, laying down its bands one slow tide at a time. Cutters wait for the low water to gather it and split each piece along the grain the water left. Coast-born clerics and salt-touched casters carry it for the calm it keeps. Each die is shaped wet and dried slow so the bands never crack.
