Hello,
It depends on what hardness do you want to test? The hardness of gems, one would use a scratch test. The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness. The basic principle, as with all common measures of hardness, is to observe the questioned material's ability to resist plastic deformation from a standard source. The Vickers test can be used for all metals and has one of the widest scales among hardness tests.
These are just examples of hardness tests, there are many! You should find out what you want to test for and find the most suitable test.

Geologists use the Mohs scale of mineral hardness to characterize the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. In this scale diamond is the hardest material and talc the softest.

He originally came up with the scale when classifying a private collection. He classified them by their physical characteristics rather than their chemical composition, using their relative hardness.
One common test that mineralogists use is the hardness test, which is often conducted using Mohs scale of mineral hardness. This scale ranks minerals from 1 (talc) to 10 (diamond) based on their ability to scratch one another. By scratching a mineral against reference materials of known hardness, mineralogists can determine its hardness and gain insights into its identity and properties.
You can determine whether a ruby or an emerald is harder by using the Mohs scale of mineral hardness. Rubies have a hardness of 9 on the Mohs scale, making them harder than emeralds which have a hardness of 7.5 to 8.
Scientists use the Mohs scale of mineral hardness to determine the relative hardness of minerals. This scale ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals. By performing a scratch test, scientists can identify a mineral's hardness by comparing it to known minerals on the Mohs scale.

Well. You can do many things like use the Mohs Hardness Scale or determine the hardness by the streak.
Geologists use the Mohs scale of mineral hardness to determine the relative hardness of a mineral by scratching it with minerals of known hardness. The scale ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
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.
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.
Mohs scale of hardness
Color: Observe the color of the mineral. Hardness: Use the Mohs scale to determine the mineral's hardness. Cleavage and fracture: Check how the mineral breaks. Luster: Determine if the mineral is metallic or non-metallic. Streak: Identify the color of the mineral's powdered form. Specific gravity: Measure the density of the mineral. Acid reaction: Test if the mineral reacts with acid.

The Mohs scale is used to determine the relative hardness of minerals.
Minerals have a fairly specific range of hardness, based on the Mohs hardness scale. The Mohs scale is based on the ability of a mineral to be scratched, or scratch, another mineral. Using the Mohs scale to determine mineral hardness is one test that can be used to help identify one mineral from others.
