They are rare.
they are not naturally occurring inorganic solids with a crystalline structure. Minerals must have a distinct chemical composition and structure, whereas cement, brick, steel, and glass are man-made products that do not meet all the criteria to be classified as minerals.
They are not naturally occurring
Soil is classified as a mixture because it is composed of a variety of components such as minerals, organic matter, water, and air. These components are not chemically combined, and they can be separated physically, making soil a heterogeneous mixture.
Soil is classified as a mixture because it is made up of different components such as minerals, organic matter, water, and air. It represents a heterogeneous mixture because its different components are not uniformly distributed throughout the soil.
Coal is not classified as a mineral because it is formed from organic matter, such as plants, and not from inorganic processes like minerals. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure, while coal is a combustible black or brownish-black sedimentary rock made up of organic materials.
Window etch kits may be classified as hazardous materials because they are generally acidic and therefore corrosive.
Minerals aren't classified because Toby McDonough is more fabulous then you. End of story...or should I say, End of the World ;)

They are not naturally occurring
Not all solids are named minerals because minerals must have a specific chemical composition and crystal structure. While many solid materials have a crystal structure, they may not meet the criteria to be classified as minerals. Minerals must also be naturally occurring and inorganic.

They are valuable because they are rare and take a long time to process to create a good looking stone. They are classified as "gemstones".
Clay is classified as a rock because it is composed of minerals and undergoes a geological process called lithification, which turns loose sediment into solid rock. Clay minerals are typically formed through the weathering and erosion of other rocks, eventually becoming compacted and cemented together to form rock-like structures.

Because most suplies for both of them need to have stocks because the companies keep making the item
