The mineral with the greatest hardness is the diamond.
Diamond is the hardest mineral, scoring a 10 on the Mohs scale of mineral hardness.

Scratching a mineral with a nail is a test of hardness. It helps determine the relative hardness of the mineral compared to known substances on the Mohs scale of mineral hardness.
Gypsum is the mineral listed at 2 on the Mohs hardness scale.
Hardness measures a mineral's resistance to being scratched.
The unknown mineral would have a hardness greater than 5.5 (the hardness of glass) but less than 7 (the hardness of quartz). Based on the Mohs Hardness Scale, the unknown mineral would likely have a hardness between 6 and 7.

The mineral with hardness 3 will get scratched.
the mineral that has a hardness of 7 is "Quarts
Scratching a mineral with a nail is a test of hardness. It helps determine the relative hardness of the mineral compared to known substances on the Mohs scale of mineral hardness.

Ruby, a variety of the mineral corundum, has a hardness of 9 on the Mohs scale of mineral hardness.
Hardness is the measure of how easily a mineral is scratched.
Hardness is better.
The relative hardness of a mineral can be best tested by conducting a scratch test against common minerals with known hardness values, such as the Mohs Scale of Hardness. By observing which mineral scratches another, you can determine the relative hardness of the unknown mineral.
Orthoclase feldspar is 6 on the Mohs scale of mineral hardness.
Gypsum is the mineral listed at 2 on the Mohs hardness scale.
Hardness measures a mineral's resistance to being scratched.
Mineral hardness is measured by how resistant one mineral is to being rubbed against another. If the mineral displays clear abrasion then it has low hardness whereas if it displays little abrasion it is a hard mineral.
