In basic terms, any tool should have a greater hardness than the material being cut or shaped. The pink granite of which the unfinished obelisk is composed has a Mohs hardness that sits between the scale of 6 and 7, (the maximum being diamond at 10) and thus is more or less the same hardness as dolerite, making the latter a poor material …

Structure and properties. Basalt is a common extrusive volcanic rock, which is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic, containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey.
