Aside from white, diamonds are also found in tones of yellow, brown, red, purple, blue and green. The color can be either natural or artificial. Natural expensive color diamonds get their coloring in various ways. The color can be due to micronutrient present in the stones, such as nitrogen, which produces a yellow diamond. The diamond might have been exposed to radiation throughout its production; green diamonds are an example of gems affected by radiation. Additions, considered unfavorable in a colorless stone, frequently contribute special tones and interesting flashes of color in a fancy color diamond. It is possible to enhance or change the natural color of a diamond. Fancy color diamonds are becoming progressively popular, so gemologists have established ways to develop affordable variations by using heat and radiation to turn brownish and yellow diamonds into vibrant show-stoppers, at an economical cost. Treatments make it possible for more customers to own these vivid diamonds, due to the fact that most natural colored diamonds are rare and pricey.

This color modification is usually long-term, but might perhaps be affected if high heat is used to set repair work. High Pressure Heat Treatment (HPHT) was first utilized to turn low-cost yellowish diamonds into expensive colored gems, but it is also used to change them into completely colorless diamonds that can be cost a much higher cost. Some business declare HPHT isn't an artificial treatment at all, calling it a technique that ends up the task nature started. Certainly diamonds are exposed to such an environment in the earth, and when the process is repeated in a man-made environment it is difficult to spot by evaluation of the stone. GIA grading reports now indicate when HTPT treatments are spotted by stating 'HPHT Annealed' or 'Artificially Irradiated' in the Origins part of a report. The FTC needs that any diamonds subjected to HPHT be labelled as such. Synthetic colored diamonds are also available. These are chemically the same as natural diamonds, but they are developed in a lab. The trick to making diamonds was discovered in the 1950s, when diamonds were manufactured practically at the same time by Swedish and American researchers. This procedure utilizes pressures of over 55,000 atmospheres and 1400C, plus molten iron to transform graphite to diamond, were essential. Presently roughly 80 tons of synthetic diamonds are produced each year by General Electric, De Beers, mainly for industrial use. Nevertheless, some business are likewise producing state-of-the-art artificial diamonds, and this procedure makes ownership of an elegant color diamond a truth for purchasers who otherwise could not pay for to buy a natural stone. For instance, a company called Gemesis specializes in producing yellow and orange fancy color diamonds. Several factors influence the cost of colored diamonds. The rarer and more intense the color, the more the diamond will cost. Unlike white diamonds, the existence or absence of inclusions is of secondary factor to consider. Colored diamonds have a grading all their own and are classified by the GIA into 9 different groups: Extremely Light, Light, Fancy Light, Fancy, Fancy Dark, Fancy Intense, Fancy Deep and Fancy Vivid. Yellow and brownish diamonds are the most common; blue, green and particularly red are the rarest and most important. Yellow and pink diamonds are the most frequently acquired, though public tastes might change in the future. Pink diamond sales got a boost from a large pink diamond ring worn by Jennifer Lopez. Celeb tastes considerably affect patterns in the location of high-end products. Yellow and brown diamonds are sometimes referred to as Champagne diamonds, and they are more economical than white diamonds. Champagne diamonds with a secondary pink color are exceptionally popular. When facing up, these stones display light to vibrant flashes of pink in their fire. These stones are offered in a gleaming variety of champagne tones, from light champagne to expensive cognac.

Natural elegant pink diamonds are unusual and represent just a fraction of one percent of the output of the Australian Argyle mine. Pink diamonds mined in India, Brazil and Africa are generally lighter in color than the extremely pink Argyle diamonds. These diamonds are mainly divided into 5 color classifications: Pink, Purple pink, Brownish pink, orange pink and Pink Champagne. Pink diamonds with no secondary coloring are the rarest and most pricey of all. By volume, the Argyle mine in the Kimberley area of Western Australia is the biggest diamond provider on the planet. It is also the world's foremost source of extremely colored pink diamonds, producing 95% of the world supply. Nevertheless, only an exceptionally small percentage of Argyle diamonds production is Pink color, in fact less than one tenth of 1 percent. The popularity of Argyle's pink diamonds has grown over the past years. At the 1989 Christie's auction in New York a 3.14 carat Argyle pink cost $1,510,000. Privately, Argyle has actually offered pink diamonds for approximately $1 million a carat. The Argyle mine, likewise a leader in the production of brownish diamonds which were formerly unwanted by consumers, was the very first to present the terms 'champagne' and 'cognac' as a marketing campaign to motivate gratitude of these stones. It seems to have worked, and brown diamonds are ending up being more pricey as they are being integrated more regularly into precious jewelry. Within an offered grade, clarity, color circulation and cut impact the final cost of the stone. Smaller sized diamonds (less than 0.80) carat can cost 10%-20% less than the rarer large gems. Extremely well cut stones and stones with a VVS or IF clarity can cost 10%-20% more. Secondary colors, such as brownish yellow, minimize cost. A good cut provides a fancy diamond its shimmer and assists to bring out the most extreme color possible. White diamonds are cut in a standard method to optimize light refraction. However, when cutting colored diamonds, the cutter usually thinks about the stone's additions, which can improve the diamond's color. Aspects and angles likewise offer color to a diamond, so the cutter must consider what shape would highlight the gemstone's finest color. The best prices are used by 'direct from the mine' wholesalers, merchants who buy either rough stone or newly cut diamonds straight from the source. Not all wholesalers will sell to personal purchasers, but the ones who do can save their clients a great deal of money.
