Shading and Variation (Natural Stone & Tile)
Floor Detective® Claims and Conditions Guide
Summary
Shading and variation describe visual differences in color, tone, veining, pattern, or surface character between individual pieces of natural stone or tile. Natural stone varies because of mineral formation, veining, quarry location, and finishing methods, while manufactured tile may vary because of glazing, printing, pigments, raw materials, and kiln firing conditions. Many ceramic and porcelain products are also intentionally designed with moderate or substantial variation to replicate natural stone, wood, or concrete visuals. Evaluation focuses on whether the installed appearance is consistent with the product type, disclosed variation range, lighting conditions, and installation layout rather than assuming the appearance represents product damage or manufacturing failure.
