mineral
a mineral is, commonly speaking, a stable chemical compound with a pretty well-defined chemical composition and a unique crystal shape that happens naturally in pure form.
Rock
the solid mineral material forming part of the surface of the earth and other similar planets, exposed on the surface or underlying the soil or oceans
Element
A chemical element is a species of atoms that have a given number of protons in their nuclei, including the pure substance consisting only of that species.
compound
a compound is a substance that results from a combination of two or more different chemical elements, in such a way that the atoms of the different elements are held together by chemical bonds that are difficult to break.
crystal
A crystal refers to the structure of a mineral, and there are many different kinds of crystalline structures.
color
The color is a constant and predictable component of the mineral. Examples are blue Azurite, red Cinnabar, and green Malachite
luster
Luster is a mineral’s ability to reflect light from the surface. It depends upon a mineral’s refractive power, degree of transparency, and structure.
streak
The streak of a mineral is the color of the powder produced when it is dragged across an un-weathered surface.
Cleavage
In mineralogy and materials science, cleavage is the tendency of crystalline materials to split along definite crystallographic structural planes.
Fracture
In the field of mineralogy, fracture is the texture and shape of a rock’s surface formed when a mineral is fractured.
Density
The density of a mineral is the ratio of its mass to its volume. It is a measure of how It is a measure of how much “stuff” is squeezed into the amount of space the mineral occupies.
Ore
Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit.
Metallic minerals
Metallic minerals are those containing one or more metals.
Non-metallic minerals
while non-metallic minerals do not contain any metal elements, but are made up of chemical elements that do not typically have metal properties or characteristics.
Gemstones
a precious or semiprecious stone, especially one cut, polished, and used in a piece of jewelry.
