Hardness and streak color are very important. The color of the mineral helps some, as well.

Color is most easily observed property of minerals but it is the least useful property for identification list two reasons why this is true and give one example for each?
1) The color of minerals (especially gasses) can change depending on the concentration of said mineral. The more diluted a mineral, the weaker or more washed the color will appear, which can change it's properties. 2) The color of a mineral can also be disturbed by impurities. Diamonds come in all kinds of colors because of microscopic differences within their individual constructs. 3) (just for fun) While "RED" and "BLUE" are univerally understood, "AQUAMARINE" and "CHARTRUSE" can be relative to the person, making them non-absolute.
What test is most reliable for identifying pyrite and gold?
Mineralogists often use the physical properties of minerals to identify them. The most reliable test in order to identify a mineral is the test for hardness.
What is a rock that contains metal or a useful mineral?
A rock containing a useful substance is called an ore. It's important to recognise that whilst a few ores contain metals (e.g. gold), most things referred to as metal ores actually contain metal compounds.

The least effective property used to identify most minerals would be the color. The color of a mineral can be altered by impurities.
What property is generally least useful in identifying minerals?
Density is the least useful property for identification because different specimens of the same type of mineral can vary in size. -Color is the least useful property for identification because it is the most obvious property.
What a property is and how you use them to classify rocks?
In classifying rocks, there are many properties that can be useful. In my opinion, either color or texture is most useful in classifying a rock or mineral.
