Do minerals have a hardness of 4 or greater?
There is a scale of mineral hardness therefore obviously some will be softer than "4" and others harder because "4" is jut one point on that scale.
The standard scale against which the hardness of minerals is rated?
Mohs hardness scale

What is the scale for the Mohs hardness scale?
Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.
What kind of mineral can scratch quartz but not diamond?
According to the Mohs scale of hardness, Diamond has a hardness of 10 and Quartz has a hardness of 7. Any mineral with a hardness greater than 7 can scratch quartz and diamond can scratch any mineral with a hardness less than 10. Corundum (hardness of 9) and Topaz (hardness of 8) are two examples of minerals that can scratch quartz but not diamond.
The standard scale against which the hardness of minerals is rated?
