Which is the pure form of carbon?

Carbon atoms in diamond are more tightly bound than in graphite (as it is the hardest material known), it is more difficult for impurities to get into the diamond lattice and as a result diamonds are often more pure than graphite. A 100% pure diamond would be totally transparent.

What are the forms of carbon?

Carbon is most commonly obtained from coal deposits, although it usually must be processed into a form suitable for commercial use. Three naturally occurring allotropes of carbon are known to exist: amorphous, graphite and diamond.
