Hard mineral composed of only carbon only. Diamond is one Mhalotrofim of carbon.Alotrof else we know about is graphite. Clean and perfect diamond is no color (transparent), but various infections (mainly nitrogen causes defects) and defects in its crystal structure can result in different colors: brown, yellow, pink and more. Rough diamond price determined by size, color and cleanliness. The price of polished diamonds is determined also by the quality of polishing.
Of mineral and diamond is the most brilliant hard: its hardness is 10 – which is the highest degree of difficulty of naturally occurring materials. The diamond is considered a natural treasure and he leads among gems. Diamond has many uses in many industries but is mainly known in its use of inlay jewelry.
Diamond and graphite carbon element only built, but their crystal shapes are different.This is called multi-formalism in Hebrew and is a feature of fixed chemical compound to appear in several crystal forms.
The stability of the diamond structure is what gives a diamond its strength and hardness.
Diamond formed deep in the ground at depths of 150 to 250 kilometers and at temperatures of 1000-1200 degrees Celsius. These conditions are only the Earth mantle beneath the oldest continents, for example in western Canada, Brazil, South Africa or Siberia. Christian Diamond magma (volcanic). After their creation by magma stay long Diamond Shell earth until they are uploaded to the surface by eruptions of magma called kimberlite.
Lab diamonds can produce correct pressures that simulate the real production process suitable for the diamond stability field. Also be possible to make diamonds at low pressure which is less pressure Atmosri hydrogen-rich environment. These diamonds are created in the laboratory are Mosoniitim and synthetic diamonds, synthetic diamond’s price can be lower by two or even more than that of natural diamond, and that both have the same shape, size and color are the same.
Measurement: The weight of diamonds is measured Beckert is 1 / 5 grams. World diamond production came in the early 90 to 100 million carats a year.The biggest diamond he H”kolinn “and he belonged to the British monarchy weighs 3106 carats are 621 grams.
is damaged and you can see with the naked eye.
Clarity: Diamond clarity level determines the level of its cleanliness. Levels are ordered highest to lowest level:FL – flawless inside or ou can be seen at a magnification of 10 and more than double.
IF- The diamond has an external defect is difficult to see an enlargement of the double 10 and can be removed by polishing.VVS1 – external defects and Interiors is hard to see them twice at a magnification of 10.
VVS2 – external defects and Interiors is hard to see them twice at a magnification of 10.
VS1 – many external and internal defects is difficult to see them twice at a magnification of 10.
VS2 – very much external and internal defects is difficult to see them twice at a magnification of 10.
SI1 – many external and internal defects could almost be seen by the naked eye.
SI2 – many external and internal defects could almost be seen by the naked eye.
I1 – Diamond damaged interior and exterior flaws that can be seen with the naked eye.
I2 – very flawed diamond interior and exterior flaws that can be seen with the naked eye.
I3 – the lowest level of clarity in which the diamond
Polishing; Diamonds are found in nature in many forms and sizes, but before scraping them are not glamorous but not glossy stone-like look. Today foreigners mainly small and large diamonds more rare. Sorting the raw by size, color and glow. After sorting send you to the center cut, and Israel is one of the most important ones.Diamond sawing was done by “her” that rotates at 5000 rpm and gradually the diamond saws. Diamond material that hard for him to have to cut another diamond, and for that use laser or diamond powder. Unprocessed raw diamond loses 66% – 50% of the mass cutting and polishing process.There are various degrees of polishing force, are determined by degree of diamond quality. For example, the shape of round brilliant cut is the hardest form of polishing and therefore most expensive.
History: The diamonds mentioned in the Bible more, as one of the jewels inlaid breastplate.9th century BC and was known for diamonds in India, and over time diamond merchants from India brought awards. Documents
were discovered in India for diamond mining and collection of taxes on diamonds BC. The earliest area was in the writings of Marcus Manilios first century AD which said “a diamond, a stone point size, more expensive than gold.” Pliny the Elder also talks about the diamonds in his book Natural History. Which describes the hardness as follows: “The diamond, the peak of wealth and luxury, who broke from no other object can not be overcome hardness, broken into pieces using a goat’s blood.” Until the fifteenth century there were no techniques for polishing and cutting diamonds had not been used diamond jewelry but as a fixture mystical or ritual. The first set with diamond engagement ring was polished as given to Mary, Duchess of Burgundy by Maximilian.
Diamond mining: Diamond formation conditions are just deep underground. Very rare diamonds fromthe area. Miners in the diamond mines in the earth or drain into the alluvial areas orrivers. Most of the diamonds traded in the world come from Africa (Republic of Congo,Sierra South Africa, Leon, the Democratic Republic of Congo, Botswana, etc.), butalso large amounts also come from Russia and Australia.
