Why Are Some Diamonds Colored

Color grading scales used by the internationally confessed laboratories (GIA & IGI for example), ranges from entirely colorless (D) to yellowish yellow or brown color (Z). Brown diamonds darker than K color are usually described using their letter grade, and a descriptive phrase, for exemplar M Faint Brown Diamonds with supplementary depth of color than Z color decline into the fancy color diamond range

The Gemological Institute of America (GIA), the American Gem Society (AGS), and the International Gemological Institute (IGI) are the three most widely declared and respected diamond classifying laboratories in the world. Each of the adjudjing laboratories own developed a thumping matching phraseology for identifying the 4 C’s of diamonds.

D to Z

Color classifying scales used by the internationally declared laboratories (GIA & IGI for example), ranges from totally colorless (D) to yellowish yellow or brown color (Z) Brown diamonds darker than K color are usually described using their missive grade, and a descriptive phrase, for prototype M Faint Brown Diamonds with more depth of color than Z color drop into the fancy color diamond range

The coloration of diamonds can be caused by several factors Impurities trapped in the diamond during its formation, the crystal framework holder of the diamond, and the exposure to radiation can all vanguard to the extensive verity of colors available in diamonds

Yellow Diamonds

Yellow diamonds are colored because of the impurities that are trapped inside diamonds when they are created If a few of the millions of carbon atoms keep been replaced by nitrogen atoms, then trestle of the diamond bequeath not be significantly altered but the clarity leave be changed The digit of color displayed is dependent on the unit of nitrogen involved.

Unlike the Type I diamonds that derived their color from impurities embedded in the diamond, Pink diamonds are considered a Type II and achieve their color from a process declared as Plastic Deformation

Type II diamonds posses thumping few if any nitrogen impurities in them They earn their coloration due to structural anomalies caused by Plastic Deformation during the crystal growth. The intense obligate changes the framework frame of diamonds and has led to the formation of Pink, and Red colored diamonds

Green Diamond

A regular diamond coming into collision with a radioactive fountain at some dab during its lifetime causes some diamonds to generate a raw coloration The circumstance required may be as much as a million years or longer. Green diamonds of this temperament are extremely unique.

The most regular tunnel of irradiation diamonds comes from alpha particles found in uranium compounds or from percolating groundwater Green spots on the surface of the diamonds or a slim uncooked film may prosper on the abrasion of the diamond after enthusiasm exposure to these particles Many times this uncooked coloration will be removed during the cutting or faceting process

Bombardment by beta and gamma rays commit color the diamond to a greater depth and in some rare juncture turn the flawless stone untried Heating to temperature to just underneath 600 degrees Celsius can sometimes furthermore model a diamond to generate a coarse ting. Higher temperature may turn the fan to a less desirable yellow or brown color

Black Diamond

Black diamonds are found only in Brazil and the Central African Republic Approximately 600 tons of conventional diamonds own been mined, traded, refined since 1900. But not a single ominous diamond has been discovered in the world’s mining fields The geological settings where diamonds are found or mined are virtually corresponding with the one exception, the Black Diamond

Black diamonds have been found to contain trace elements of nitrogen and hydrogen. The inspect recognized in 2006 analyzed the hydrogen in dark diamond samples using infrared-detection utensils and found that the cipher indicated that the mineral formed in a supernova explosion monastic to the formation of the Solar System These diamonds were formed by carbon-rich cosmic dust in an environment brewing carbon stars The diamonds were incorporated into solid bodies that subsequently fell to Earth as meteorites.
