Because granite is between a 6 and 7 on the mohs scale it would be able to scratch other types of stone that have lower ratings such as marble.
Marble vs granite hardness.
The main difference is that granite and marble are made of different minerals that perform differently in regards to chemical resistance and hardness.
They are natural stones unlike say engineered quartz silestone so both marble and granite surfaces are susceptible to chipping and st.
Marble will also scratch more easily since it scores a four on mohs scale of hardness versus granite s rating of seven.
Granite vs marble comparison.
As a result marble is less porous and slightly stronger than limestone but still less durable than granite.
Granite has a mohs hardness rating of seven.
Marble is limestone that has been compacted and heated over millions of years.
