Orthoclase Feldspar.
In a hand sample/specimen you can the properties used to identify minerals are luster, diaphaneity, color, streak, luminescence, play of colors, crystal shape, tenacity, cleavage, hardness, specific gravity and density, magnetism, electrical properties, reaction to acid.
The mineral that can scratch feldspar and can be scratched by garnet is quartz. Quartz has a hardness of 7 on the Mohs scale, making it capable of scratching feldspar, which has a hardness of 6. Meanwhile, garnet has a hardness of around 6.5 to 7.5, allowing it to scratch quartz but not all varieties of garnet will scratch quartz.
yes, minerals can only be scratched by other minerals with hardness equal or greater. thus this explains why a diamond can be cut and "polished" by dust or smaller diamonds
Pyrite is harder than bornite. Pyrite has a hardness of 6 to 6.5 on the Mohs scale, while bornite has a hardness of about 3 to 3.5. This makes pyrite significantly more resistant to scratching and abrasion compared to bornite.
Orthoclase Feldspar.
Orthoclase feldspar is 6 on the Mohs scale of mineral hardness.
The mineral might be pyrite, which has a hardness lower than calcite, a metallic luster, and cubic cleavage. Pyrite's hardness is around 6-6.5 on the Mohs scale, compared to calcite's 3. It forms cubic crystals and has a brassy color.

Streak. The 6 properties of minerals are streak, hardness, crystal form, color, cleavage/fracture, and luster. Hope that can answer your question:)
Pumice has a hardness of about 6 on the Mohs scale of mineral hardness.
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 scale for the mineral hornblende is 5-6.
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.
Pumice has a hardness of about 5 to 6 on the Mohs scale.
A mineral with a hardness of 6 on the Mohs scale can be scratched by anything harder than a 6, such as minerals with a hardness of 7 or higher. It will not be scratched by minerals with a hardness of 5 or lower.
Orthoclase feldspar is 6 on the Mohs scale of mineral hardness.
