How Natural Stone Variation Should Be Handled
Variation is why people choose granite — and the top source of disputes when it isn't managed. A process for setting expectations.
Every granite slab is a cross-section of geology, not a print run. Color, veining, mineral movement and shade genuinely differ between samples, slabs and production bundles — and a good procurement process treats that as a feature to be managed, not a defect to be argued about.
Set the range, not the ideal
A single showroom sample defines an ideal; a control range defines an agreement. For shade-critical projects, approve a light and dark boundary sample (or photographs of both ends of the bundle) so everyone knows what 'in range' means before production starts.
Match the process to the stone
Consistent stones can be ordered from samples with confidence. Veined and dramatic stones should be ordered only from current photography of the actual slabs, with seam layout reviewed on those images. Sequential slabs from one block should be specified whenever a single space uses multiple slabs.
Put it in the paperwork
Reference approved slab numbers and images in the order. Include a variation clause that acknowledges natural range while committing to the approved bundle. This is exactly the notice Kasini includes on every product page — because expectations set in writing are the cheapest quality control there is.
