The harder rock is diamond
I don't know if diamond is considered a rock but otherwise diamond is the hardest mineral. Diamonds are created by the compression of minerals deep inside the the crust (Thinnest layer of the Earth)
Diamond. Diamond is the only mineral on this list. Granite is an intrusive igneous rock, meaning that it formed beneath the surface of the earth. Marble is a metamorphic rock, which means that it formed from another type of rock, or "parent rock," through subjection to intense heat and/or pressure. Limestone is a sedimentary rock composed of calcium carbonate and can often be the parent rock for marble. Please note that the Mohs hardness scale does not apply to rocks. It only covers minerals.
The hardest rock is PANTERA, or Diamonds. Depending on your question.
The hardest substance that is naturally occurring is a diamond. However, there are harder substances that have been made by scientists in labs.
The hardest substance in a rock would be the hardest mineral of which the rock is composed.
Diamond
The diamond is the hardest rock (or mineral).
The softest rock is generally talc, with a Mohs hardness of 1, while the hardest rock is diamond, with a Mohs hardness of 10. Other common rocks fall in between, such as gypsum (2), calcite (3), quartz (7), and feldspar (6-7).

Feldspar is a 6 on the hardness level and diamond is the hardest t 10. Feldspar is not very heavy- about the weight of granite or quartz (the average rock)

Granite is generally considered to be harder than marble. Granite is a very hard, durable rock composed mainly of quartz, feldspar, and mica, while marble is a softer rock primarily made of calcite. This difference in composition gives granite greater resistance to scratching and other forms of wear compared to marble.
