The difference of the test is that each test a a different porpose.
Hardness and streak color are very important. The color of the mineral helps some, as well.
Yes, all different samples of that mineral will have the same cleavage.
Different minerals have different colors, actually.
Yes each different mineral will have a unique set of physical properties.
A mineral is a naturally occuring chemical compound. A mineral is different from a rock/boulder which can be an aggregate of minerals, or non minerals and does not have a specific chemical composition as a mineral does
There are several different tests that can help identify minerals. You can use any of them to determine the sample.
The powder indicates the true color of the mineral and is an aid in mineral identification. That can also be called a streak.
they all could be different colors it just depends on the texture of them
It is the diamond.
Color.
Specimen color is the least reliable method of mineral identification. Better characteristics are streak, density, and crystal structure.
Color is the least reliable of a mineral's characteristics used in its identification.
Color is the observable color of a mineral specimen in natural light. Streak is the color of a mineral when powdered. The color of a specific mineral specimen may be different than its streak color. Because many impurities can alter the color of a mineral, but not the streak, streak is a more accurate predictor in mineral identification.
From the shape of a mineral crystal, it can be classified into one of the six mineral crystal systems, which is an aid to its identification.
