Diamond - Daemon.

Long before it was a tile, the diamond was a sound. The Greeks called the shape rhombos, after a small wooden blade tied to a cord and whirled through the air until it hummed, a noise used in old rites to call something unseen into the room.

It is a shape that seems made for storytelling, with room on every tile for a small inlaid figure to settle, and the freedom to place those figures wherever the story needs them, scattered loosely like wildflowers in a meadow or returning in careful rhythm like the figures in an old woven border.

And when the diamonds are left without figures, the colour takes over the telling. Glazes laid side by side can drift from one shade into another like a field changing with the season. They guide the eye across the wall, so that even a surface with no creatures at all still seems to have somewhere it is going.
