Use for diamonds
- Industrial cutting and abrasion: because diamond is the hardest natural substance, it is widely used on saw blades, drill bits, grinding wheels and polishing tools to cut, grind or shape hard materials. (Also common: gemstones/jewelry, heat sinks in electronics, high-pressure anvils.)

The five criteria that define a mineral
1. Naturally occurring — it must form by natural geological processes (not manufactured in a lab).
2. Solid — it must be a solid under normal Earth-surface conditions (so not a liquid or gas).
3. Inorganic — it is not made by living organisms (organic substances like coal are excluded).
4. Definite chemical composition — it has a specific or narrowly variable chemical formula (e.g., quartz = SiO2).
5. Ordered internal atomic structure (crystalline) — atoms are arranged in a regular, repeating pattern that defines crystal form and physical properties.

These five together distinguish minerals from rocks, glasses and manufactured materials.
