Coal and diamond are both allotropes of carbon, which is a mineral.
coals minerals illite clay, pyrite, quartz, and calcite.

Some minerals contain carbon, such as graphite and diamonds, however while they both contain carbon, the diamonds density is far greater.
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.
Diamonds are minerals, composed of the element carbon.
Diamonds are formed from carbon, which is a mineral.
The two hardest minerals besides diamonds are moissanite and lonsdaleite. Both of these minerals have a hardness level that is close to that of diamonds on the Mohs scale of mineral hardness.
Diamonds are pure carbon.
Diamonds are formed from carbon.

Diamonds are composed of carbon atoms arranged in a specific crystal structure. Pure diamonds are made entirely of carbon with no other minerals present.
Diamonds formed from carbon in the lab, are diamonds formed from the mineral carbon.
