Diamonds: The World’s Top Fancy Color Producing Countries.
DSO Archive publishes a research on color diamonds, on the elements that influence the color variations and where they are mined. The geological requirements involved to yield fancy colors are uncommon rendering naturally occurring shades infrequent. Trace elements, structural irregularities and radiation combine to mutate the colorless crystal structure of diamonds known as crystal lattice.
Brown diamonds occur when the crystal lattice is deformed in combination with radiation and nickel impurities.
It is the most commonly available diamond color and it is extracted in Angola, Australia, Borneo, Brazil, and Congo. Australia’s mines are known to produce large quantities and some fractions of the production across the African continent result in browns.
Australia and the Argyle mine are known for producing some of the best hues of Champagne Brown diamonds.
Orange diamonds occur when an uncommon structure of the nitrogen causes the crystal lattice to retain the blue and yellow lights of the spectrum and to release the orange. The color combinations of Orange diamonds include yellow, brown or pink.
Orange diamonds are largely mined in Africa and Congo produces some of the most vivacious and rich hues.
Yellow diamonds occur when the atoms of nitrogen present in the crystal lattice combine in a particular structure that retains the blues of the spectrum and releases the yellows. The color combinations of Yellow include orange, green or brown.
They are mined mostly in Africa between Angola, Democratic Republic of Congo, Central Africa and Sierra Leone; they are also extracted in Australia, Brazil and Borneo.
Sierra Leone is an important producer of yellow diamonds and one of their mines, Zimmi, extracts some of the most magnificent speciments with the highest color saturation namely Zimmi Yellow.
Pink diamonds occur when heat and pressure cause the crystal lattice to alter in its structure in such a way that the green light of the spectrum is retained enhancing the pink. The color combinations of Pink diamonds include orange, brown or purple.
Pink diamonds are mined in Australia, Brazil, Canada, Russia, Siberia, South Africa and Tanzania.
Australia and specifically the Argyle mine produce some of the most rich and vibrant varieties of Pink with the highest color saturation.
Violet diamonds occurrence is related to the presence of hydrogen, although further studies are needed to asses the dynamics between the elements.
They are very rare, mostly small in size and they are typically unearthed in Australia in the Argyle mine.
Diamonds in the Violet color that show no traces of grey tend to be the rarest.
Purple diamonds occur when heat and pressure cause the crystal lattice to alter in its structure in such a way that the green light of the spectrum is retained enhancing the purple. The color combinations of Purple diamonds include orange, brown or pink.
They are very rare, they tend to be small in size and they are primarily mined in Australia, Brazil, Canada and Russia.
The Argyle mine in Australia and the Siberian region in Russia tend to produce some of the finest Purple diamonds.
Red diamonds occur when the crystal lattice is distorted causing the green light of the spectrum to be retained and the pink to be released at an extraordinarily high saturation.
Red diamonds are extremely rare and are mined in Australia, Brazil, Russia, and India.
Australia’s Argyle mine is consistent in producing Red diamonds however exceptional it is to find them.
Blue diamonds occur due to the presence of boron in the carbon causing the retention of the red, yellow and green lights of the spectrum to release the blue color. The color combinations of Blue diamonds include grey, green or violet.
They are more steadily mined in South Africa, India, Brazil and Central Africa however in most countries it is a rare find.
South Africa and the Cullinan mine produce Blue diamonds with the most consistency and they are known for the richness and intensity of their color.
Green diamonds occur when the crystal lattice is exposed to natural radiations causing the carbon to retain the yellow and red lights of the spectrum and release green. The color combinations of Green diamonds include blue, grey and yellow.
They are very rare to occur in nature and they are mostly mined in Africa and South America as well as India.
Black diamonds occur when the crystal lattice is dense with graphite inclusions that are great in number and evenly distributed throughout the diamond rendering the gemstone often milky or cloudy.
They are rare and they are mainly unearthed in mines in Central Africa alongside other color diamonds.
Gray diamonds occur due to the presence of boron in the crystal lattice causing the retention of the red, yellow and green lights of the spectrum to release the grey color. The color combinations of Grey diamonds include blue, green or violet.
They are very rare and primarily mined in Africa, Brazil, Russia and South Africa.
