Bookmatching
Bookmatching is the technique of opening two consecutive slabs like a book so that their mirror-image vein patterns create a symmetrical composition across a joint. It is widely used for feature walls, fireplace surrounds, and bathroom vanities. Successful bookmatching requires that slabs remain in sequence from the same bundle and that the installer understands which face to flip.
When a block is sawn, the slabs lie face to face, so two neighboring slabs carry almost the same veins. For a bookmatch, the factory polishes the two faces that touched at the cut. Laid side by side, one slab mirrors the other across the joint, like the pages of an open book. Four consecutive slabs can be matched the same way, across and up and down, for a larger wall.
It only works when the slabs stay together and in order. A missing number, a slab sold to another customer or a slab with a crack breaks the pattern. That is why yards keep bookmatched slabs as one bundle, numbered in cutting order, and sell them as a set.

Noria Strata keeps every slab's number in its bundle, in cutting order, and the Portal shows the slabs that go together in the order they will be laid.
