Travertine and limestone share a calcite-based composition, yet their appearance tells different geological stories. Travertine forms around mineral springs, leaving open pores, layered bands, and linear patterns, while limestone can contain fine grains, fossils, or shell fragments from ancient marine environments. These materials bring warm beige, cream, gray, and earthy tones to floors, walls, fireplaces, patios, and architectural details.
