EXIR STONE GROUP
Natanz White Granite has a gray or gray background and black and dark gray (peppery) grains are uniformly spread throughout its surface. This type of granite is called cotton flower. But this stone has lower grades as well, with black spots (gland) and a halo of gray color in it. Natanz Black Granite, as its name suggests, has a black or smoky background, which is slightly different in different color types along with long white faded lines. This stone is very resistant, stubborn and stable against cold, heat, weathering, sunlight and harsh environment. Nowadays, epoxy materials are used to make this granite look better.
