No, diamond is a mineral. Coal is an igneous rock; it can take years for coal to form.
Both coal and diamonds are formed from carbon. However, diamonds are formed under intense pressure and heat deep in the Earth's mantle, while coal is formed from plant material that has been compressed and heated over millions of years.
Diamonds formed in laboratories are formed from carbon, which is an element. By definition, a mineral occurs naturally. So no, a lab-formed diamond is not a mineral.
Both diamonds and coal are made primarily of carbon atoms. However, the arrangement of the carbon atoms is what gives diamonds their hardness and brilliance, while coal is a sedimentary rock formed from compressed plant matter over millions of years.
Coal and diamonds are both forms of carbon.
Both diamonds and coal consist of carbon atoms.
Some minerals contain carbon, such as graphite and diamonds, however while they both contain carbon, the diamonds density is far greater.
Coal and diamond are both allotropes of carbon, which is a mineral.

Diamond fits the definition of a mineral in that it is naturally occurring, a solid, composed of an element or combination of elements, and has a crystalline structure. Many minerals contain carbon. Graphite, the mineral, is also pure carbon but with a different crystalline structure.
Coal and diamonds are both forms of carbon.
Both diamonds and coal consist of carbon atoms.
No, diamonds and graphite are not polymorphs of silicon. Diamonds are a polymorph of carbon, while graphite is also a polymorph of carbon. Silicon does not form diamonds or graphite as polymorphs.
Diamonds and granite are both formed deep within the Earth's crust under high pressure and temperature. They are both composed of mineral elements, with diamonds being a crystalline form of carbon and granite being a mixture of different minerals such as quartz, feldspar, and mica. Both diamonds and granite are valued for their hardness, durability, and aesthetic appeal.
Diamonds and graphite are both allotropes of carbon.
Carbon is the element found in both diamonds and pencil lead. In diamonds, carbon atoms are arranged in a crystal lattice structure, making it a prized and valuable gemstone. In pencil lead, carbon is in the form of graphite, which is a softer allotrope of carbon used for writing and drawing.
