Natural diamonds are the hardest substances that exist in nature and are composed of pure carbon. They come in a variety of crystal forms, including octahedral, rhombic dodecahedral and their polymorphs. Natural diamonds are usually colorless and transparent, but they may also appear in different colors such as yellow, blue, green and black due to the presence of impurities. They sometimes have obvious triangular pits on their crystal faces and, due to varying degrees of fusion erosion suffered during the formation process, the crystal faces are often curved, and the crystal prisms and faces are blunted, making the crystal shape often rounded. An important difference with synthetic diamond is that more than 95% of natural diamonds have the characteristic 415 nm peak in the visible spectrum, while synthetic diamonds are missing this peak.

The price of natural diamonds is affected by a number of factors, including color, clarity, cutting process, and weight. As a result, their price per meter (or per carat) can vary greatly. High-quality natural diamonds, especially those that are colorless and clear and internally flawless, are extremely valuable and are used in jewelry making and high-end technological applications.

Synthetic diamonds are synthesized through artificially controlled conditions and have similar physical and chemical properties to natural diamonds, but there are significant differences in value between the two. The rarity and aesthetic value of natural diamonds make them valuable as gemstones and for high-end industrial applications, whereas synthetic diamonds are primarily used for industrial purposes, such as cutting and grinding tools.
