Maderno Travertine is a highly versatile material, with light and dark neutral tones and classic travertine movement. This stone does contain a wide variation of color and structure.
Our stone materials are crafted by nature. Variations in color, pattern, texture and veining should be expected. That is one of the things that makes every single fireplace a one-of-a-kind work of art. Shade variation is natural and perfect shade matching cannot be guaranteed. If you have concerns, your best bet is to order a sample from current stock (as older samples may not be reflective of current stone shading).
