Granite comes in at a 6 to 7 on the mohs scale meaning it is relatively hard.

The igneous rock is comprised of mostly quartz and feldspar along with smaller amounts of various other minerals. The visible crystals in marble give it a characteristic granular surface and appearance but there are other properties used to identify the rock. These rocks are composed of many distinct minerals. Marble was used because it is soft enough to be carved but hard enough to survive for a while.

Granite is a very hard granular crystalline igneous rock which consists mainly of quartz mica and feldspar and is often used as building stone. With a curve it s highly unlikely that it s going to chip. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.
