Chevron mosaic tiles
Chevron and herringbone are routinely confused. In a chevron the chips are mitred so their ends meet in a continuous point; in a herringbone they are plain rectangles overlapped at a right angle. The chevron gives the cleaner arrow and the more formal wall, and it is the one that needs a level substrate to look right.
That extra cut is why the range is smaller — every chip is angled at the factory rather than simply sawn. Both of ours are honed Carrara White with grey, which suits the pattern: too much veining and the point where the chips meet stops reading as a point.
