Luster is simply a way of describing how a mineral reflects light. No minerals absorb 100% of light, so all minerals have some degree of luster.
No, just the hardness.
Nope. It is actually the hardness. I'v been trying to find out what the Luster scale is myself....:S
Olivine is 6.5-7 on the Mohs scale of mineral hardness.
the mohs hardness scale
Friedrich Mohs is famous for creating the Mohs scale of mineral hardness. He formulated a scale of one to ten and assigned each mineral a value. This eventually became the basis for the Mohs scale.
The Mohs mineral scale was named after German mineralogist Frederich Mohs (1773-1839)
It's called the Ore
The Mohs scale measures the hardness of a mineral. Kaolinite, which is a clay mineral and part of the group of industrial minerals, has a Mohs scale value of 2-2.5.
Diamond, with a hardness of 10 on the Mohs scale.
Ruby, a variety of the mineral corundum, has a hardness of 9 on the Mohs scale of mineral hardness.
Talc is the softest mineral on the scale
Iodine is not recognized as a mineral, and therefore is not assigned a number on the Mohs Scale of mineral hardness.
