The hardness of the mineral pyrite, or Fool's Gold, is about 6 on the Mohs hardness scale. That's a little harder than a steel knife blade, but not as hard as the mineral quartz
Orthoclase has a hardness of 6 on the Mohs scale of mineral hardness. It is a common mineral found in granite and other igneous rocks.
The hardness of pegmatite can vary depending on its mineral composition, but it typically falls between 6 to 7 on the Mohs scale of mineral hardness. This means that pegmatite is harder than steel but softer than quartz.
Augite has a hardness of around 5 to 6 on the Mohs scale of mineral hardness. It is a common mineral found in igneous rocks and is known for its dark green to black color.

The Mohs hardness scale of serpentine is between 2.5 to 4. It varies depending on the specific type of serpentine mineral.
Orthoclase has a hardness of 6 on the Mohs scale of mineral hardness. It is a common mineral found in granite and other igneous rocks.
Fluorite is the number 4 mineral on the Mohs scale of mineral hardness, above calcite and below apatite.
Feldspars generally have a hardness of 6 on Mohs' hardness scale.
The hardness of pegmatite can vary depending on its mineral composition, but it typically falls between 6 to 7 on the Mohs scale of mineral hardness. This means that pegmatite is harder than steel but softer than quartz.
