Diamond is in the isometric crystal system, which is reflected in the usually found octahedral or cubic crystal form. The external crystal class is 4/mBar32/m, whereas the space group designation is F41dBar32/m. Twins are frequent on the {111} plane. It has perfect four directional cleavage, adamantine shine, and both a high refractive index, 2.42, and specific gravity, 3.52. Color is generally pale yellow to colorless, but can also be brown, blue, green, orange, red, and black.

Diamond might be up to 3 billion years old, which is much older than their surface host rock (Harlow, 1998, p. 60). Diamond crystallization originates some 200 kilometers, or 320 miles, under the surface and the disaggregated crystals are merely transported to the surface via kimberlite and lamproite pipes (Harlow, 1998, p. 54). These igneous host rock formations are generally cylindrical in shape and act as a conduit from the Earth's mantle to the contintental crust.

Diamonds are distinguished between various types, Ia, Ib, IIa, and IIb.

Diamond's greater optical properties and hardness has earned this mineral the highest respect in both industry and jewelry. It has a long tradition of invincibility and therefore the Greek name, adamas.

For instance, when asked about the option of synthetic diamonds for their jewelry, a chief executive of Carat brand said that they aim to offer affordable jewelry.
