Colored diamonds are mostly found from the Earth after mining. It can also be created under special environments, mostly in laboratories where they mimic the conditions that are developed in them naturally. These diamonds can mostly be found in any shades of the rainbow and there are around twenty-seven hues for them as listed by the Gemological Institute of America.
The available array of diamond hues helps the jewelers for matching the names of the colors with the fashionable nicknames in the vogue. For example, brown diamonds are often called champagne diamonds whereas yellow diamonds are known as canary diamonds and orange diamonds are known as pumpkin diamonds.
These names are mainly used for the colored diamonds to make them more appealing. In accordance with the definition of most jewelers about the prevailing fashion, these nicknames can often change as well. For example, some of the diamond jewelers use “chocolate” for “champagne” for referring to brown diamonds.
The stones that are mainly used in baguette ring usually acquire their color from certain chemical elements or some kind of peculiarity like in the case of chameleon diamonds. Even a single carat diamond stone necessitates a lot of carbon atoms for bonding. All the atoms must be of carbon which can help in the formation of colorless diamonds as even a small quirk can create a colored diamond.
The presence of nitrogen in diamonds makes it yellow in color whereas the presence of boron gives it blue color. Also, that natural radiation that is absorbed from the adjacent rocks usually trap the electrons thereby making the surface of the color green. Red and pink hues appear because of the changes in the electron structure during the journey to the surface.
The conditions while making the diamonds in the industry by replacing many things from nature also contribute to the formation of these diamonds. The color treatments even are done on the diamonds in laboratories for augmenting their color. For example, a yellow-colored diamond needs a thin blue coat for neutralizing the actual color thereby giving it the impression of a high color grade. The irradiation processes that are done on these diamonds can turn the color of the natural diamond to be more blue, green, yellow, red or pink.
The color grades of the diamonds are usually issued by the GIA which describes the color of fancy diamonds in three ways – hue, tone, and saturation. The pressure and natural radiation could often make the color of the diamond more intense and, each color has a particular symbolism.
