Natanz Black Granite: Natanz Black Granite is one of the more expensive granite stones. Its dark color makes it suitable for use as a tombstone. For home applications, it is often combined with bright colors. The granite comes in various designs: black with white stripes, a black background with white spots, or completely black. Some samples feature black spots, called nodules, which are darker than the base color of the stone. Fewer nodules generally indicate higher quality. Like other granites, Natanz Black Granite has low porosity and high hardness, which results in low adhesion with mortar. It is highly resistant to acids and detergents, making it ideal for use in kitchens and cabinets. It absorbs very little water, making it suitable for bathrooms and toilets. It is recommended for stepping stones due to its high resistance to traffic. Additional applications include grave markers, staircase walls, parking lot floors, hotels, commercial centers, and high-traffic areas. Natanz Black Granite is almost impervious to wear and impact. It features a completely black background with varying degrees of lightness, black nodes, and sometimes white lines. Compared to other black granites such as Chayan, Tuyserkan, and Sarkan, Natanz Black Granite offers a more reasonable price.
