Scientists use the hardness test, and more specifically Mohs Hardness Scale, named after a Freidrich Mohs, a German mineralogist. Mohs Hardness Scale test can scale from 1 to 10, where 1 is softest and 10 is hardest.
Use the scratch test.
it refers to the mohs scale
A mineral's resistance to being scratched is known as it's hardness. You can determine hardness by scratching it with another material whose hardness is already known. If it can be scratched, then the hardness is lower. If the unknown leaves a scratch on the known material, then its hardness is higher.

The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. Ithardnesses
mohs scale of hardness
Diamond is the hardest naturally occurring mineral and can scratch all other minerals. Talc is the softest of minerals and cannot scratch any other mineral.
It is the Mohs scale of mineral hardness. It characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. The scale assigns numbers 1-10. 10 being the hardest of minerals(e.g. diamonds), and 1 being the softest minerals(e.g. talc). Generally minerals with a H<5 are softer minerals and minerals H>5 are harder.
Diamonds are proven to scratch all minerals including itself.
The Mohs scale of mineral hardness is generally used to determine the hardness of a mineral. The Mohs scale rates the ability of mineral to scratch or be scratched by another mineral.

The Mohs Scale of Hardness is used to measure hardness of a mineral, which is its resistance to scratching. It is a quantitative scale, which relies on the relative hardness of other minerals . Higher numbered minerals scratch lower numbered ones. You can use every day objects like a glass plate, a knife, or a nail to distinguish hard and soft. Hard minerals scratch glass, but can't be scratched with a knife blade of a nail. Soft minerals will not scratch glass, but can be scratched with a knife blade or masonry nail. You can purchase hardness kits to help make these distinctions.
