Many people are starting to favor the fancy, vivid colored diamond gem stones over the traditional transparent, or white, diamond. Some diamonds are found in their natural colors when they are mined, others become colored by gemologists and jewelers during a treatment process. In order to make them more affordable to the average consumer, companies have begun color treating diamonds of lower grades in order to take a less desirable yellow or brownish tinted diamond and make it into a beautiful, brightly colored diamond.
Colored diamonds can be treated by a process called irradiation, which uses a high heat system to alter the color of a diamond. Other diamonds are treated by painting.
While many diamonds are inspected and valued based on their colorless qualities, there are people who prefer the fancy colored diamonds that come in vivid hues of greens, yellows, reds, pinks and all the different colors in between.
Some colored diamonds are that way naturally. If a diamond has nitrogen in it, it often has a yellow tint to the stone. If the gemstone has been effected by radiation, the gem may turn green.
Other colored diamonds have been treated to obtain their color, and this allows people with lower budgets to purchase the fancy colored diamonds. Gemologists have found ways to alter the colors of diamonds, called treated diamonds, to get any shade or hue desired.
