Bone's rank may vary depending on how dense it is; often it averages between 4 and 6, but denser bones with more collagen may rank higher, while sparser bones, such as those in flying birds, may rank lower.
This fact is what makes a hypothetical "bone age" possible; if rocks are unavailable or too soft, the gifts of the dead may more than compensate.
This scale was proposed by the Austrian geologist Friderich Mohs.
It's called the Ore
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
Azurite has a hardness of 3.5 to 4 on the Mohs hardness scale.
Arkose has a hardness of around 6 on the Mohs scale.
No, just the hardness.
The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.
Nope. It is actually the hardness. I'v been trying to find out what the Luster scale is myself....:S

The hardness is 3-4 on Mohs scale.
Topaz is number 8 on the Mohs scale.
The Mohs scale compares the hardness of an object or substance.
Rutherfordium is a synthetic element and its hardness on the Mohs scale is unknown as it is difficult to measure. The Mohs scale is typically used to rank naturally occurring minerals based on their scratch resistance, so it may not be applicable to man-made elements like rutherfordium.
The softest material in the mohs scale is talc
