Yes, there can be slight variations in color for China Grey Granite. While the base color is typically a medium to dark grey, there can be variations in shade and intensity within that range. Some slabs may have subtle flecks or veins of other colors such as white, black, or even hints of blue. These variations in color can occur due to differences in the composition of the stone or the specific quarry it is sourced from. It is always recommended to view samples or pictures of the specific slab or batch of China Grey Granite before making a selection if color consistency is important for your project.
