Are diamonds and coal related?
Diamond is a pure form of carbon, one of its allotropes (the others are graphite and buckminsterfullerene). Coal is a complex mixture of carbon and organic compounds. The percentage of carbon depends on the age of the coal. (There is more in older coals like anthracite.) The exact structure of the carbon in coal is poorly understood, but it does not seem to be like diamond.
