The material of the memorial is also an important factor to consider. This brochure shows memorials in a vast range of materials including Granite, Sandstone and Marble. These all have differing characteristics, for example, Granite is the strongest material and will weather better when compared with Sandstone and Marble which may stain in certain conditions (i.e.near a tree Or a hedge). Some Granites are more porous than others, meaning they may become darker when wet, however we can offer you advice on the vast range of materials available. When choosing Black Granite, we recommend Premium Khammam Ebony Black which is a dense Black and is not dyed.
