Choosing a Slab at the Yard
Go and See It Standing Up
Slabs are stored upright in bundles and viewed vertically, which is not how they will be used, but it is the only way to see the whole surface at once. Ask for the slab to be pulled out and lit. A stone that reads as subtle in a bundle can be dramatic in isolation, and the reverse happens just as often.
Wet It
Water approximates the appearance of a sealed and polished finish and it is the single most useful thing you can do at a yard. Colours deepen, veining gains contrast, and features that were invisible dry become obvious. Every experienced buyer does this and yards expect it.
Look for Fissures and Pits
Natural stone contains fissures, which are mineral boundaries, and pits, which are small surface voids. Both are characteristic rather than defective and neither is a crack. What matters is whether a fissure runs somewhere structurally awkward, such as across where a sink cutout will be, which is a layout decision made against the actual slab.
Check the Whole Bundle
If your kitchen needs more than one slab, they must come from the same block and preferably be consecutive. Ask to see every slab you are buying, not just the top one. Colour drift within a bundle is normal and it is very visible when two drifted pieces meet at an inside corner.
Mark the Layout
Take a photograph of the whole slab and mark on it roughly where the island, the sink run and the cutouts will fall. Bring it to the fabricator. That single image prevents the most common disappointment in stone work, which is a feature vein ending up in an offcut or disappearing under a hob.
Confirm the Reference in Writing
Slabs carry a block and bundle reference. Get it onto your order. Trade names are marketing and change between suppliers, but the reference identifies the physical stone you stood in front of, and it is the only thing that lets you check on delivery day that you got what you chose.
