The are all composed of carbon (although coal commonly also contains other elements such as sulphur).
Graphite, coal and diamonds are all thought to be products of the decay and compression of vegetable matter from millions of years ago. Diamonds progress from coal.

carbon
Graphite is Carbon, the chemical symbol is C. There are many forms of graphite, such as coal, and diamonds. Even the human body contains carbon. It is dug straight out of the earth just like mining coal and diamonds.
Coal, pencil lead, and diamonds are all forms of carbon. The difference lies in how the carbon atoms are structured. In coal, carbon atoms are loosely attached, while in diamonds they are tightly bonded, resulting in the hardness of diamonds. Pencil lead is a mixture of graphite (which is a crystalline form of carbon) and clay.
yes all of them are minerals.Another AnswerNone of them are minerals: coal, diamonds and graphite are formed from the mineral carbon. There is a class of minerals, according to Wikipedia: "The halide minerals are the group of minerals forming the natural salts."
Carbon is the mineral found in coal, graphite, and diamonds. The different arrangements of carbon atoms lead to the diverse properties of these materials.
All forms of carbon.
Diamond, coal, graphite, coke and buckminsterfullerene are composed primarily of carbon and are insoluble in water.
Well to be very upfront diamond is very heated and compressed carbon (coal graphite) while graphite is more "pure" carbon than diamonds
Coal, graphite and diamonds are all allotropes of carbon and are stable at room temperature.
Carbon. Coal has a few different types and grades, but hard anthracite coal is almost pure carbon. Same as graphite, soot and diamonds.
