Both graphite and sugar charcoal may be used to create fake diamonds, however sugar charcoal is an amorphous carbon, whereas graphite is crystalline. Amorphous carbon does not have any specific crystal structure and is very flexible. Amorphous carbon can be made into diamonds via the process of thermal treatment. The diamond powder is mixed with a binder (typically cobalt) and pressed into tablets which are placed in an oven where they are heated to about 1000'C (1832 F). As the tablet cools, the binder hardens and binds the powder together. Only high-quality amorphous carbon will yield diamond products when subjected to this treatment. Lower quality carbon will not heat up during processing and will produce non-diamond products instead. Graphite, on the other hand, will not yield diamond products even after subjecting it to high temperatures. This is because graphite has a highly ordered crystalline structure that prevents it from becoming amorphous at room temperature. However, under high pressure liquid nitrogen can be forced through graphite, turning it into an amorphous form that can then be converted into diamonds at lower temperatures. This method is used by geologists to extract fluid inclusions containing pure diamond from deep within rocks.
