The quality of a diamond's cut is widely considered the most important of the four Cs in determining the beauty of a diamond; indeed, it is commonly acknowledged that a well-cut diamond can appear to be of greater carat weight, and have clarity and color appear to be of better grade than they actually are.
Synthetic diamonds, also referred to as lab-grown diamonds, are created using advanced technological processes such as High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD). These methods result in diamonds that are chemically and physically identical to natural diamonds , offering the same brilliance and durability.
In the paradox of value, it is a contradiction that it is cheaper than diamonds, despite diamonds not having such an importance to life. The paradox of value, also known as the diamond–water paradox, is the paradox that, although water is on the whole more useful in terms of survival than diamonds, diamonds command a higher price in the market.
These diamonds are then weathered from the source and swept away by alluvial processes (transported by water) to a source that becomes a diamond deposit. Alluvial diamond deposits are mined after removing overburden from the top of the rich, diamond-gravel layer. Roughly 10 percent of diamonds are mined from alluvial diamond placer mines. [8]
Lonsdaleite (named in honour of Kathleen Lonsdale), also called hexagonal diamond in reference to the crystal structure, is an allotrope of carbon with a hexagonal lattice, as opposed to the cubical lattice of conventional diamond. It is found in nature in meteorite debris; when meteors containing graphite strike the Earth, the immense heat and ...

The production and distribution of diamonds is largely consolidated in the hands of a few key players, and concentrated in traditional diamond trading centers, the most important being Antwerp, where 80% of all rough diamonds, 50% of all cut diamonds and more than 50% of all rough, cut and industrial diamonds combined are handled.

Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest, and ...
