Discovering Colored Gems
Color Treated Diamonds
Many people are starting to favor the extravagant, dramatic colored gemstones over the classic clear, or white, diamond. Some gemstones are uncovered in their organic colors when they are mined, many others can be shaded by gemologists and jewelers during a treatment process. In order to make sure they are more affordable to the average customer, specialists have started color treating diamonds of lower grades in order to take a less prestigious yellow or brownish colored gem and turn it into the most stunning, brightly colored diamond.
Colored diamonds can be treated by the procedure called irradiation, which utilizes a very high thermal system to alter the color of a diamond. Other jewels are treated by painting them.
The Natural Range of Fancy Color
Even though diamonds are inspected and valued based on their clear qualities, there are individuals who favor the intense colored diamonds that come in vivid shades of greens, yellows, reddish, pink along with 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 and thus will be classified as yellow diamonds. Sometimes, exposure to natural radiation causes stones to appear quite green..
Other colored diamonds which have been treated to obtain their color allows people with lower budgets to purchase the fancy colored diamonds. Gemologists have found ways to alter the colors of diamonds to get any shade or hue desired.. Grading colored gems is more complex than grading the clear variety due to the stacking of the color intensity.. The first part of the color grading process is the identification of the primary color range, eg blue, pink etc.. Secondarily, the intensity of that particular color range is graded on a scale. A very intense, naturally colored diamond is more rare than a less intense diamond, and therefore more expensive. A treated diamond will cost less than a naturally colored diamond in most instances..
Synthetic Diamonds
Most diamonds are found and mined by miners, However, it is quite possible for the diamond to be created by a scientific process. While a synthetic diamond is still a "real diamond", they are created within a laboratory instead of by nature in a mine.
Colored Diamond Names
Since fancy colored diamonds are available in so many different shades, it can sometimes be difficult to interpret the name of the diamonds color. You can quite regularly see a cross referencing of color such as a "greenish blue". Each name has a primary color description, and some have a secondary color description If another color is mentioned with an 'ish', that would be the secondary color. If you come upon a diamond labeled "brown red", then the diamond will have equal amounts of both colors seen through the stone.
Recently It has become a very popular choice to buy yellow diamond engagement rings, from the range of canary yellow diamonds and other fancy yellow diamonds.
