From Wikipedia, the free encyclopedia. Redirected from Diamond symbol. Form of rhombus. Diamonds can also symbolize wealth and status.

As the early royal families, aristocrats, and wealthy families held collections of diamonds, and it is not uncommon to find diamonds of adorn wallets, bags, phone cases, or even clothing.

While diamonds have become more popular and prevalent, they, at the same time, remain a luxury product that is reserved for those who can afford it.

Diamonds, besides love and wealth, can represent the symbol of extravagance and beauty. For example, from Hollywood award shows to presidential dinners, diamonds may be found on accessories and jewelry e.

The way the light sparkles and reflects on a gemstone of the diamond can be immediately captivating that gives a sense of elegance as well.

Unfortunately, diamonds have also come to represent some of the worst tragedies and conflicts in our lifetime. The gemstone mining has resulted in child slavery and child soldiers, and even civil wars in Sierra Leone and Liberia.

Most diamonds come from the Earth's mantle , and most of this section discusses those diamonds. However, there are other sources.

Some blocks of the crust, or terranes , have been buried deep enough as the crust thickened so they experienced ultra-high-pressure metamorphism.

These have evenly distributed microdiamonds that show no sign of transport by magma. In addition, when meteorites strike the ground, the shock wave can produce high enough temperatures and pressures for microdiamonds and nanodiamonds to form.

A common misconception is that diamonds are formed from highly compressed coal. Coal is formed from buried prehistoric plants, and most diamonds that have been dated are far older than the first land plants.

It is possible that diamonds can form from coal in subduction zones , but diamonds formed in this way are rare, and the carbon source is more likely carbonate rocks and organic carbon in sediments, rather than coal.

Diamonds are far from evenly distributed over the Earth. A rule of thumb known as Clifford's rule states that they are almost always found in kimberlites on the oldest part of cratons , the stable cores of continents with typical ages of 2.

The Argyle diamond mine in Australia , the largest producer of diamonds by weight in the world, is located in a mobile belt , also known as an orogenic belt , [67] a weaker zone surrounding the central craton that has undergone compressional tectonics.

Instead of kimberlite, the host rock is lamproite. Lamproites with diamonds that are not economically viable are also found in the United States, India and Australia.

Kimberlites can be found in narrow 1 to 4 meters dikes and sills, and in pipes with diameters that range from about 75 m to 1.

Fresh rock is dark bluish green to greenish gray, but after exposure rapidly turns brown and crumbles. They are a mixture of xenocrysts and xenoliths minerals and rocks carried up from the lower crust and mantle , pieces of surface rock, altered minerals such as serpentine , and new minerals that crystallized during the eruption.

The texture varies with depth. The composition forms a continuum with carbonatites , but the latter have too much oxygen for carbon to exist in a pure form.

Instead, it is locked up in the mineral calcite Ca C O 3. All three of the diamond-bearing rocks kimberlite, lamproite and lamprophyre lack certain minerals melilite and kalsilite that are incompatible with diamond formation.

In kimberlite, olivine is large and conspicuous, while lamproite has Ti- phlogopite and lamprophyre has biotite and amphibole. They are all derived from magma types that erupt rapidly from small amounts of melt, are rich in volatiles and magnesium oxide , and are less oxidizing than more common mantle melts such as basalt.

These characteristics allow the melts to carry diamonds to the surface before they dissolve. Kimberlite pipes can be difficult to find.

They weather quickly within a few years after exposure and tend to have lower topographic relief than surrounding rock. If they are visible in outcrops, the diamonds are never visible because they are so rare.

In any case, kimberlites are often covered with vegetation, sediments, soils or lakes. In modern searches, geophysical methods such as aeromagnetic surveys , electrical resistivity and gravimetry , help identify promising regions to explore.

This is aided by isotopic dating and modeling of the geological history. Then surveyors must go to the area and collect samples, looking for kimberlite fragments or indicator minerals.

The latter have compositions that reflect the conditions where diamonds form, such as extreme melt depletion or high pressures in eclogites. However, indicator minerals can be misleading; a better approach is geothermobarometry , where the compositions of minerals are analyzed as if they were in equilibrium with mantle minerals.

Finding kimberlites requires persistence, and only a small fraction contain diamonds that are commercially viable. The only major discoveries since about have been in Canada.

Since existing mines have lifetimes of as little as 25 years, there could be a shortage of new diamonds in the future.

Diamonds are dated by analyzing inclusions using the decay of radioactive isotopes. Depending on the elemental abundances, one can look at the decay of rubidium to strontium , samarium to neodymium , uranium to lead , argon to argon , or rhenium to osmium.

Those found in kimberlites have ages ranging from 1 to 3. The kimberlites themselves are much younger.

Most of them have ages between tens of millions and million years old, although there are some older exceptions Argyle, Premier and Wawa. Thus, the kimberlites formed independently of the diamonds and served only to transport them to the surface.

The reason for the lack of older kimberlites is unknown, but it suggests there was some change in mantle chemistry or tectonics.

No kimberlite has erupted in human history. Such depths occur below cratons in mantle keels , the thickest part of the lithosphere.

These regions have high enough pressure and temperature to allow diamonds to form and they are not convecting, so diamonds can be stored for billions of years until a kimberlite eruption samples them.

Host rocks in a mantle keel include harzburgite and lherzolite , two type of peridotite. The most dominant rock type in the upper mantle , peridotite is an igneous rock consisting mostly of the minerals olivine and pyroxene ; it is low in silica and high in magnesium.

However, diamonds in peridotite rarely survive the trip to the surface. They formed in eclogite but are distinguished from diamonds of shallower origin by inclusions of majorite a form of garnet with excess silicon.

Diamond is thermodynamically stable at high pressures and temperatures, with the phase transition from graphite occurring at greater temperatures as the pressure increases.

Thus, the deeper origin of some diamonds may reflect unusual growth environments. In the first known natural samples of a phase of ice called Ice VII were found as inclusions in diamond samples.

The mantle has roughly one billion gigatonnes of carbon for comparison, the atmosphere-ocean system has about 44, gigatonnes. It can also be altered by surface processes like photosynthesis.

This variability implies that they are not formed from carbon that is primordial having resided in the mantle since the Earth formed.

Instead, they are the result of tectonic processes, although given the ages of diamonds not necessarily the same tectonic processes that act in the present.

Diamonds in the mantle form through a metasomatic process where a C-O-H-N-S fluid or melt dissolves minerals in a rock and replaces them with new minerals.

Diamonds form from this fluid either by reduction of oxidized carbon e. Using probes such as polarized light, photoluminescence and cathodoluminescence , a series of growth zones can be identified in diamonds.

The characteristic pattern in diamonds from the lithosphere involves a nearly concentric series of zones with very thin oscillations in luminescence and alternating episodes where the carbon is resorbed by the fluid and then grown again.

Diamonds from below the lithosphere have a more irregular, almost polycrystalline texture, reflecting the higher temperatures and pressures as well as the transport of the diamonds by convection.

Geological evidence supports a model in which kimberlite magma rises at 4—20 meters per second, creating an upward path by hydraulic fracturing of the rock.

As the pressure decreases, a vapor phase exsolves from the magma, and this helps to keep the magma fluid. Then, at lower pressures, the rock is eroded, forming a pipe and producing fragmented rock breccia.

As the eruption wanes, there is pyroclastic phase and then metamorphism and hydration produces serpentinites. Although diamonds on Earth are rare, they are very common in space.

In meteorites , about three percent of the carbon is in the form of nanodiamonds , having diameters of a few nanometers. Sufficiently small diamonds can form in the cold of space because their lower surface energy makes them more stable than graphite.

The isotopic signatures of some nanodiamonds indicate they were formed outside the Solar System in stars. High pressure experiments predict that large quantities of diamonds condense from methane into a "diamond rain" on the ice giant planets Uranus and Neptune.

Diamonds may exist in carbon-rich stars, particularly white dwarfs. One theory for the origin of carbonado , the toughest form of diamond, is that it originated in a white dwarf or supernova.

The most familiar uses of diamonds today are as gemstones used for adornment , and as industrial abrasives for cutting hard materials. The markets for gem-grade and industrial-grade diamonds value diamonds differently.

The dispersion of white light into spectral colors is the primary gemological characteristic of gem diamonds. In the 20th century, experts in gemology developed methods of grading diamonds and other gemstones based on the characteristics most important to their value as a gem.

Four characteristics, known informally as the four Cs , are now commonly used as the basic descriptors of diamonds: these are its mass in carats a carat being equal to 0.

A large, flawless diamond is known as a paragon. A large trade in gem-grade diamonds exists. Although most gem-grade diamonds are sold newly polished, there is a well-established market for resale of polished diamonds e.

Secondary alluvial diamond deposits, on the other hand, tend to be fragmented amongst many different operators because they can be dispersed over many hundreds of square kilometers e.

The De Beers company, as the world's largest diamond mining company, holds a dominant position in the industry, and has done so since soon after its founding in by the British businessman Cecil Rhodes.

De Beers is currently the world's largest operator of diamond production facilities mines and distribution channels for gem-quality diamonds.

As a part of reducing its influence, De Beers withdrew from purchasing diamonds on the open market in and ceased, at the end of , purchasing Russian diamonds mined by the largest Russian diamond company Alrosa.

Further down the supply chain, members of The World Federation of Diamond Bourses WFDB act as a medium for wholesale diamond exchange, trading both polished and rough diamonds.

Once purchased by Sightholders which is a trademark term referring to the companies that have a three-year supply contract with DTC , diamonds are cut and polished in preparation for sale as gemstones 'industrial' stones are regarded as a by-product of the gemstone market; they are used for abrasives.

Recently, diamond cutting centers have been established in China, India, Thailand , Namibia and Botswana. The recent expansion of this industry in India, employing low cost labor, has allowed smaller diamonds to be prepared as gems in greater quantities than was previously economically feasible.

Diamonds prepared as gemstones are sold on diamond exchanges called bourses. There are 28 registered diamond bourses in the world.

Diamonds can be sold already set in jewelry, or sold unset "loose". Mined rough diamonds are converted into gems through a multi-step process called "cutting".

Diamonds are extremely hard, but also brittle and can be split up by a single blow. Therefore, diamond cutting is traditionally considered as a delicate procedure requiring skills, scientific knowledge, tools and experience.

Its final goal is to produce a faceted jewel where the specific angles between the facets would optimize the diamond luster, that is dispersion of white light, whereas the number and area of facets would determine the weight of the final product.

For example, the diamond might be intended for display or for wear, in a ring or a necklace, singled or surrounded by other gems of certain color and shape.

Some of them are special, produced by certain companies, for example, Phoenix , Cushion , Sole Mio diamonds, etc. The most time-consuming part of the cutting is the preliminary analysis of the rough stone.

It needs to address a large number of issues, bears much responsibility, and therefore can last years in case of unique diamonds.

The following issues are considered:. After initial cutting, the diamond is shaped in numerous stages of polishing. Unlike cutting, which is a responsible but quick operation, polishing removes material by gradual erosion and is extremely time consuming.

The associated technique is well developed; it is considered as a routine and can be performed by technicians. Those flaws are concealed through various diamond enhancement techniques, such as repolishing, crack filling, or clever arrangement of the stone in the jewelry.

Remaining non-diamond inclusions are removed through laser drilling and filling of the voids produced. And the firm created new markets in countries where no diamond tradition had existed before.

Ayer's marketing included product placement , advertising focused on the diamond product itself rather than the De Beers brand, and associations with celebrities and royalty.

Without advertising the De Beers brand, De Beers was advertising its competitors' diamond products as well, [] but this was not a concern as De Beers dominated the diamond market throughout the 20th century.

De Beers still advertises diamonds, but the advertising now mostly promotes its own brands, or licensed product lines, rather than completely "generic" diamond products.

Brown-colored diamonds constituted a significant part of the diamond production, and were predominantly used for industrial purposes. They were seen as worthless for jewelry not even being assessed on the diamond color scale.

After the development of Argyle diamond mine in Australia in , and marketing, brown diamonds have become acceptable gems. Industrial diamonds are valued mostly for their hardness and thermal conductivity, making many of the gemological characteristics of diamonds, such as the 4 Cs , irrelevant for most applications.
