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.

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.

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.

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.
