What is a colored diamond?
Colored diamonds are diamonds that have a noticeable body color when viewed in a facing position. Brown and yellow are the most common colors in natural colored diamonds. Diamonds with natural pink, blue, orange, green, red, and violet bodycolors are extremely rare.
Of the 100,000 diamonds, only a few will have a very rare color. The color can have any intensity between "very light" and "vivid". To be considered a "colored diamond," the color must be noticeable when the diamond is facing upwards. Black, gray and white diamonds are also possible.
Fancy Red Argyle Isla Diamond
Argyle Isla: Argyle Isla is a 1.14 carat red radiant cut diamond mined from the Argyle Mine in Western Australia. It is one of the most valuable diamonds in the world on a per-carat dollar basis. It was a part of selling Argyle Tender Heroes in 2017. Copyright 2017 by Rio Tinto.
Colored diamond prices
The combination of rarity, beauty, and keen buyer interest drives the prices for colored diamonds. The rarest colored diamonds are often sold at millions of dollars per carat. They have a greater value for their size than almost any other material. At the same time, some colored diamonds are being sold at prices that many people can afford.
The most affordable colored diamonds have a brown, gray or black color. Among colored diamonds, these colors are the least rare and the most expensive. Attractive diamonds in these colors often sell for a few thousand dollars a carat. They sometimes sell for less than diamonds on the D-to-Z colorimeter that are similar in size, cut, and clarity.
Yellow diamonds are next in rarity. They are much rarer than brown, gray and black diamonds. Yellow diamond is considered by many people to be the most beautiful yellow gemstone due to its exceptional brightness, fire and luster. Beautiful, fancy yellow colored diamonds can often be purchased for $ 5,000 to $ 10,000 per carat in sizes less than two carats. Many people are not aware that yellow diamonds are an option in this price range. Here's their chance to get colored diamonds at a surprising price.
Blue, green and pink diamonds are much rarer than yellow diamonds. Another rare move is the orange, purple, and red diamonds. These colors often sell for more than $ 100,000 per carat, and those of the highest quality ones sell for more than $ 1,000,000 per carat.
The price of a colored diamond depends more on its color. Also important is the color saturation and uniformity of color across the face of the gem. Usually people with pure color are more desirable than those with modified colors. As with all diamonds, the size of the gemstone and the quality of the cut are very important as well.
In the past decade, colored lab-grown colored diamonds and processed natural color diamonds have become more and more popular in the market. These diamonds are not rare, and they are sold at lower prices than natural diamonds with colors of natural origin. To ascertain the identity of what you are purchasing, gem laboratories can examine diamonds to determine if they are natural or laboratory-grown. Labs can also determine the origin of a diamond's color. These lab services have a very low cost compared to that of diamond. Identification and classification by a reputable laboratory is an essential part of any colored diamond treatment.
Common causes of color in diamonds
Pink pink is a rare natural color in diamonds. It occurs when a diamond is subjected to pressure inside the earth, and these forces cause jets of the carbon atom to slip into the diamond crystal. When light passes through planes, red light is selectively transmitted. The red light appears pink when the selective transmission is weak. Seldom is a selective transmission powerful enough to reproduce the color red.
Red diamonds are extremely rare in nature, and they are the most valuable diamonds when they are pure in color. Like the pink diamond, they were subjected to a stress that distorted the diamond crystal lattice, causing planes to slip off the carbon atom. When light passes through the displacement levels, the red wavelengths of the light are selectively transmitted. Poor red light transmission will result in a pink diamond.
Orange diamonds are very rare. The defect (s) that produces the orange color has not been identified with certainty and may vary from one orange diamond to the next. The disadvantages of orange diamonds cause them to selectively absorb blue light and selectively transmit the orange color.
Yellow yellow is the second most common natural color in diamond. The color is usually caused by nitrogen atoms replacing the carbon in the diamond crystal lattice. This defect causes diamonds to selectively absorb blue light and selectively transmit yellow.
The color of green diamond green is very rare in nature. The color usually develops when high-energy radiant diamonds emitted from nearby radioactive mineral grains penetrate. The radiation ejects the carbon atoms from their position in the diamond crystal lattice
