Why Are Some Diamonds Colored

Color classifying scales used by the internationally admitted laboratories (GIA & IGI for example), ranges from wholly colorless (D) to pasty yellow or brown color (Z). Brown diamonds darker than K color are usually described using their letter grade, and a descriptive phrase, for pattern M Faint Brown Diamonds with fresh depth of color than Z color dive into the fancy color diamond range

D to Z

Color evaluating scales used by the internationally proclaimed laboratories (GIA & IGI for example), ranges from completely colorless (D) to wan yellow or brown color (Z) Brown diamonds darker than K color are usually described using their missive grade, and a descriptive phrase, for paradigm M Faint Brown. Diamonds with further depth of color than Z color plunge 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 mesh rack of the diamond, and the exposure to radiation can all govern to the panoramic verity of colors available in diamonds

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 threatening diamond has been discovered in the world’s mining fields The geological settings where diamonds are found or mined are virtually selfsame with the one exception, the Black Diamond

Black diamonds own been found to contain trace elements of nitrogen and hydrogen. The scan declared in 2006 analyzed the hydrogen in minatory diamond samples using infrared-detection apparatus and found that the quantity 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 near carbon stars The diamonds were incorporated into insolvable bodies that subsequently fell to Earth as meteorites
