A diamond is a natural mineral that is composed of carbon. It is also chemically inert to most acids and alkalis. Like graphite, lonsdaleite ("hexagonal diamond"), and the fullerenes, a diamond is an allotrope of carbon and, no matter what its size, each diamond can be considered to be a single molecule of carbon. Physical properties still provide the main means for identification of minerals, however, though they are no longer used to group minerals (from the example above, corundum is an oxide while diamond is a pure element, so by Dana's system, they are in separate groups). Diamonds are usually coloures, some are tinged yellow, some blue, brown, green, pink and even black. When you are looking for diamonds, you should educate yourself about a diamond's characteristics.
