Where Natural Diamonds are Found ?

 Where Natural Diamonds are Found ? 

Natural resources diamonds have been discovered in some 35 countries around the world over several continents.
Every piece of diamond has an interesting story behind it. Russia, Botswana and South Africa is the world’s largest diamond producer of gem quality and Australia are the biggest industrial diamond producer. The most notable diamond deposits in Africa.

Africa – South Africa, Namibia, Botswana, the Democratic Republic of Congo, Angola, Tanzania and Sierra Leone, India, Russia – Siberia, South America – Brazil Australia – Northern and Western Australia China United States – Arkansas, Colorado and Wyoming Canada .
Diamonds are exposed to the hardest of all stones. Those who will be ways to dig these stones, even put to find many lives at risk in the diamond mining industry. Central and Southern African countries traditionally known as the world’s largest supplier of diamonds. A diamond is very expensive for polishing and design. But with the discovery of diamond reserves in other countries, it is proved that Africa is the only continent that host diamond-producing countries. Moreover, it is no longer to hold the top land where most of the diamonds are found.

Fancy Colored Diamond Formation

Fancy Colored Diamond Formation 

The physical requirements for color a diamond naturally very rare, for every natural color diamond, there are 10,000 colorless ones. The formation of natural diamond color is a process that the presence of several trace elements and distortions of the typical diamond crystal (so-called plastic deformation) is required. In creating a diamond, when an object, such as boron, nitrogen interaction with their carbon atoms, the color change. Natural radiation and pressure on a diamond structure intensify color . Since scientists have never perceive formed a natural diamond, to determine the exact nature and amount of required variables is almost impossible.

HDPL - Fancy Colored Diamonds

Even a one carat Diamond to bind require billions of carbon atoms, and all of these atoms must be carbon to produce a colorless Diamond . Colored there are so many colors and intensities in nature may optionally patterns. The reason for this is not only can trace minerals influence of color, but also variations in how much pressure to be in the earth to produce diamond and radiation levels mantle layer may also affect the diamond colors. In order to produce a certain color, to thousands of variables in the right quantities at the right moment. For example, as mentioned above, boron produces natural blue diamonds, while hydrogen produces violet to purple diamonds. Also nitrogen in the right amounts to produce orange or yellow diamonds. Diamond has been scientifically proven to red to brown category which have an internal structure compressed much more than the average white diamonds. According to the Natural Color Diamond Association, Argyle diamond shows nearly ten times as many high pressure grit more traditional diamonds. This granulate is proof of the high pressure ratios well above what it would take to form a white diamond.

Colored diamonds are found, both in the nature and in the laboratory. The physical requirements for color a diamond naturally very rare, for every natural color diamond, there are 10,000 colorless ones. The formation of natural diamond color is a process that the presence of several trace elements and distortions of the typical diamond crystal (so-called plastic deformation) is required. According to GIA, only 10,000 natural diamond is a diamond colored external D Z gradation spectrum. Colored diamonds can be found in almost every color of the rainbow. GIA shows 27 shades for natural colored diamonds. Different colors are available allowed jewelers to the name of the color to what is in fashion, like the fashion industry is the introduction of “new” colors: champagne (brown), pumpkin (orange), canary ( yellow), etc. GIA color grading issue. It describes the color of the fantasy diamond in three ways: pure spectral colors of the diamond (tint); light or dark tone (tone); and color strength and purity on a scale from neutral to live (saturation). Natural radiation and pressure can intensify diamond color.

Here are Some of the Colors Formation Details by which conditions and Ingredients Fancy Colored Diamonds are Formed .

Brown, Red & Pink Diamonds :- 

RED , BROWN, & PINK diamonds owe their color to a combination of intense pressure and heat. While still buried deep in the earth, these factors lead to distortions in the crystal lattice that absorb green light, whereby as a result of a pink hue. Ultra-rare red diamond, which, in essence, just deep colored pink diamonds, has the same cause color. Structural defects in diamond lattice give brown diamonds their color, because they absorb lack of light. The presence of nitrogen can also be a diamond a brown tint.

HDPL - PINK TO RED COLOR DIAMONDS

The terms “champagne diamonds” (lightly tinted brown diamond) and “cognac diamond” (darker brown diamond) was established to better promote these loose brown diamonds. Brown diamonds are found in Australia, Africa and Siberia. Red is the rarest diamond color and the most expensive diamond color. Red hues are believed to have been changes in the electron structure under diamond trip to the surface.

Gray  &  Blue Diamonds :- 

Blue diamonds get their color from the BORON. When this contamination is present, binds to the carbon in the crystal structure, the red, yellow and green color absorbs spectrum. Boron is a factor which are the same size as the carbon, and can be easily found in small quantities in a diamond. However, when present Low Boron and nitrogen levels very low boron gifts diamond blue. Nickel or high concentrations of hydrogen hypothetical causes of the blue color in some diamonds. The most notable my blue diamond is the Cullinan, Pretoria, South Africa.

HDPL - Grey to Blue Diamonds

Trace elements such as boron into carbon structure can Form Grey Diamond . Grey Diamond which not Properly Saturated can also be a Black Diamond .

Green Diamonds :- 

For Green Diamonds , It is only in the last leg of the journey to the earth’s surface which diamonds get their green color. Just as  about to leave the top layer of the earth’s crust, these stones absorb naturally occurring radiation, causing them to reflect a green tint by absorbing red and yellow light. Natural green diamonds are extremely rare, with less estimated ten every year on the market. While some green diamonds have a trace amount of nickel mixed in their carbon, the green color in the diamond by the natural radiation from the nearby rock, which captures electrons to create a green surface. Since the colored part is the outermost layer, one of the natural green lost during polishing.

Violet and Purple Diamonds :- 

HDPL - Violet & Purple Diamond
Until now, all researchers are convinced that the temporary color purple and violet diamond crystal deformation. However, it is believed that the presence of hydrogen may be partially responsible for the color tone. Pure Purple is the second rarest color of the diamond. Natural purple diamonds account for 1% of the diamonds mined in Siberia Mir kimberlite fields. Most are just a pale purple, but some show a strong purple color. Although there are several theories about why some diamonds show a purple color, many researchers believe that natural purple diamonds are formed due to re-growth plastic deformation during the trip from the Earth’s mantle to the surface by magma. Experts able to say a natural purple diamond of a purple diamond treated by examining the distribution of color. Treated stones are saturated with color everywhere; natural purple diamonds have a concentration of color along the deformation lamellae.

Orange and Yellow Diamonds :- 

The remarkable shade of orange and yellow diamonds can be attributed to an element: the nitrogen.Yellow diamonds are very common, but the most vivid yellow diamonds are mined in South Africa. While forming a diamond, the nitrogen atoms such that the blue light is absorbed, causing a yellow coloration. A particular class of nitrogen atoms is also responsible for shading orange diamond, but will absorb light in the blue and yellow spectrum.

HDPL - Yellow Diamonds

 

The yellow color comes from the absorption of nitrogen; nitrogen atoms are quite similar carbon atoms they are easy to transport carbon can take in their process. Nitrogen suspected training its modifiers history Diamonds. Throughout orange, yellow diamonds which are not enough to live be called beautiful yellow diamonds are “improved” with blue, hoping to pass as a colorless diamond.

Black Diamonds :- 

Unlike most other colored diamonds are formed, a black color of the diamond which is not related to the trace elements. Small inclusions of graphite and iron to create clusters “black” color. While other colored diamond transparent, the many inclusions in a diamond black means typically opaque. As a black diamond necessarily have inclusions, breaks more easily than some other gem quality diamonds. Black diamonds in nature usually not always black. They can include clear, white or gray pieces. In order to improve the black color, diamonds are exposed to high pressure and high temperature treatment (HPHT). Black diamonds will exhibit the fire and brilliance of a diamond white or transparent colored diamonds.

HDPL - Black Diamond

They do not hang as predictable as the most diamonds. The people who are involved in the cutting and polishing diamonds black many of the difficulties are gem quality, and most of them are explained exclusively industrial use. This is also the lighter parts of diamond darker. Other methods include staining of diamond or irradiation.

Diamonds – What is Diamond and How are Diamonds Formed ?

What is Diamond And How it is Formed ? 

Hundreds of millions of years ago eruption of magma from the mantle propelled natural diamonds closer to the surface . The funnel-shaped areas carved out magma eruption known kimberlite pipes, named after the first formation in Kimberley, South Africa discovered . Gradually at the top of the tubes eroded below expose diamond . Erosion can also wear diamonds from its original location in river and coastal areas. In its crudest form, which means diamond ore does not look like the shiny nuggets on top engagement rings . Diamonds are sorted, cut and polished to bring out its luster . Diamonds are not created from the compressed trees and vegetation that coal produces as popularly believed .

Experiments and the high density of the dots represent only can be molded together under tremendous heat and pressure . The only places where these conditions exist deep below the earth’s surface, about 150 km to 200km (90 to 120 miles) in an area called the mantle beneath the Earth’s crust where an abundance of carbon atoms . The pressure here in combination with temperatures between 900-1300 on the Celsius scale forced to crystallize together the carbon atoms in a cubic (isometric) arrangement creates diamonds .

Recession Crumbled Surat’s Diamond Market Glaze

diamond Recession

Diamond industry in Surat, one of the main sources of foreign income and livelihoods of millions of people, has reached a difficult time . A number of polishing units are in the grip of recession, fear of closure is looming large for some .

A decrease in external demand and stagnating prices of polished diamonds that against the rising cost of raw stones is the culprit .

“The overseas demand is very low and there is no increase in prices of polished diamonds, if compared with (the increased prevalence) of rough diamonds from 2014,” president of the Association of Diamond Surat Dinesh Navadia told PTI .

Navadia called the descent as “unprecedented”.

“This happens quite a time, but after three or four months, usually improves the situation . This time, the crisis has lasted a long time,” he said, adding that the rumors are only worsen the situation .

While Godhani Gems, a unit of diamonds with 1,500 employees, has closed shop, has about 25 units gone bankrupt, he said .

On the situation of workers of diamonds, Navadia said it is difficult for unskilled or semi-skilled to find jobs in a recession workers .

Aniruddha Lidbide analyst diamond trade, could not agree more. “It is much less demand (of polished diamonds) of China, Southeast Asia, the Gulf, Europe and the United States. Because of that, a lot of inventory remains with the diamond industry,” says Lidbide .

“The prices of roughs (rough stones), which is the raw material for cut and polished diamonds, has risen to 65-70% in three years . Prices of diamonds in the same way, has not been polished gone up . It is stagnant, so the profit margin was very thin, “Lidbide said .

Moreover, some of the owners of the diamond industry have diverted money to other companies, which also harms (industry) he said .

“In recent years, most of the diamond industry has reoriented its economy to another business . They have invested mainly in the real estate industry, and also in the stock market or trade in oil and currency” , Lidbide said.

He said it was difficult for Surat diamond traders to obtain credit from banks, which also add to the problem .

“Many companies suspended after 2008, and one of the main among them was Vicente diamond . In 2013, to pay a sum of Rs 4,500 crore and has left the country . A very strong for many banks blow was given . Some 12 13 banks had been funding diamond Vicente “Lidbide said, adding that the default of many others have forced a depreciation of about Rs 8,000-10,000 crore in the last 3-4 years .

“More than that, the financial main bank, Antwerp Diamond Bank Belgium closed its operations on June 13 there is also a big blow to the diamond industry, as it was an important source of funding,” he said .

Synthetic diamonds that are very similar to the original, produced mainly by Russia and China, have also affected the company, Lidbide added .

“Those who have worked with 100% capacity has now reduced its activity by 50-60%, depending on usage and inventories they have,” he said .

Chairman of jewelry and stones Export Promotion (GJEPC) Sanghvi Chandra was also on the same page .

“International demand for polished diamond has decreased, which has created the situation of decline . This may continue for 3-4 months,” he said .

“We have known a recession that many times, but we left it,” he said .

Pravin Nanavati, owner jewelers based in Surat She also blames the fall in exports for the current state .

“About 90% of the diamond business is based on exports . But as foreign demand declined in the last couple of months our industry slowdown,” Nanavati PTI .

He also said that synthetic diamonds make people doubt in buying fake diamonds .

“The government should establish a single university for the diamond industry, offering courses development and human resources management,” he suggested .

Since hundreds of thousands of people who depend on the industry, Nanavati said “this is the time that the government took measures in the interest of one of the industries that produce higher incomes.”

Diamond Formation

How Are Diamond Formed ? 

Diamonds are made of carbon crystallized temperature and extreme pressure. They were formed millions of years ago in the molten rock in the earth at depths greater than 160 km. After their formation, diamonds brought to the surface in the ascending magma strong volcanic activity. When the magma cooled conical tubes with blue rock called kimberlite again. Over the years, the wind, rain, snow and ice eroded kimberlite and diamond indicator minerals and released. Advance and retreat of glaciers sometimes dispersed and eroded materials hundreds or thousands of kilometers away are transported.HDPL - Diamond Formation

Geologists believe that diamonds in all commercial diamond deposits were formed Earth in the mantle and delivered to the surface of the volcanic eruptions of deep origin. These eruptions produce kimberlite and lamproite pipes that is coveted by diamond prospectors. Diamonds degraded and eroded from these eruptive deposits are now found in sedimentary deposits of rivers and coasts.

Some diamonds can be found in these secondary deposits of laundered materials called alluvial deposits. However, the main source of these precious stones in kimberlite itself. To find these diamonds rocks, and therefore the results geologists chemistry of mineral indicators, anticipated regional studies of ice and geophysics analysis.To date, over 500 kimberlites found in Canada are combined and many are in our remote northern areas .

The formation of natural diamond requires very high temperatures and pressures. These conditions occur in limited areas of the mantle of the Earth around 90 miles (150 kilometers) below the surface, where the temperature is at least 2,000 degrees Fahrenheit (1,050 degrees Celsius). This pressure environment temperature critical for diamond formation and stability is not present worldwide. Instead, it is believed that is mainly present in the mantle beneath stable inside the continental plates.

Diamonds are formed and stored in these Diamond Stability Zones come to the surface during volcanic eruptions deep source. These eruptions heartbreaking parts of the mantle and quickly bring them to the surface. This type of eruption is extremely rare and has not occurred since scientists have been able to recognize.
