What is the least reliable way to identify a mineral?

The color test is the least reliable test because many different minerals have similar colors. A similar test to color is the streak test.

What is the most reliable way to identify a mineral?

How do you tell if something is a rock or mineral?

What’s the difference between rocks and minerals? Edit. A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids.
