A little history

Diamonds, of course, a very wide range of colors. Most people know the system and colorless diamonds GIA grading used for classification of body color of the diamond ... You know, D, E, F, etc. The system of grading is used, only the most common color of the corpus luteum of diamonds, however, filed at any time of the diamond variety of colors such as pink, blue, green, etc., and then to discover that the diamond is called "Fancy diamonds".

Natural fancy diamonds can sometimes be very costly, and far more expensive than colorless diamonds of comparable size. A very good example of fantasy diamond-known 45.52-carat diamond fancy blue Hope Diamond, freshwater pearl jewelry, set in the Smithsonian Museum of Natural History in Washington, DC.

Colored diamond diamond expanded 100% natural, which changed its color. And best of all, diamonds are color enhanced in a variety of colors at very reasonable prices!

A little history

For many, many years was known as a diamond color can be "improved" by a few colored substance on the surface of the diamond, and as if by magic ... Diamonds, which are noticeable yellow color changed to attractive near colorless diamonds. Unfortunately, this type of color change Increased diamond body to remove its original color when the colored substance unwittingly.

In recent years, technology has improved the color diamond is very high tech. Now you can completely change the color of a diamond! These processes must be permanent, since it does not remain stable when exposed to every day under normal conditions. Color will not fade from sunlight or washed with harsh chemicals.

How do we do?

As a result of these procedures is the availability of commercial diamonds. Diamond lesser value will be a diamond, color, lower body, and sometimes has a faint light. Color expansion processing plants diamonds to know if they start with a certain type of diamond and changes over time, they end up with a certain color, but it is not always the case. It is the science that some art is necessary in the process ... the only method that yields consistent results, the coating process.

Three processes, as follows-

Process # 1 - colored diamonds HPHT high pressure and high temperature (HPHT) treatment can improve the color of some species of brown diamonds and increasing their value. General Electric is a process that is almost mechanical modeling creative point of diamonds in nature. Diamond color enhanced to a very high temperature will be heated to very high pressure has stabilized. Irregularities in the crystal structure, the new version of the diamond, color is produced.

As conditions of HPHT diamond are very similar to the original line, only a well-equipped laboratory able to identify positively reinforced this type of colored diamonds. HPHT was first used to turn yellow diamond fancy colored diamonds more marketable, but now it is also used for unpopular brownish diamonds into more desirable for colorless diamonds of color.

Process # 2 - irradiated diamond color OK ... does not start, all excited because you saw the word irradiated! It's safe to 100%, which is very similar to that used for food by making it to maintain the flow of gamma rays. The process of diamond color is enhanced in several ways, but the results are all the same. You start with a basic color (P, Q, R, etc.) 100% natural diamonds that is already cut and polished, it is then subjected to electron flow. During this part of the process of diamond on a very dark color again, because some of the atoms in the crystal structure of diamonds is currently broken, and this influenced the path of light through the diamond. In addition, the diamond goes through controlled heating (annealing) process, which can transfer some of these atoms (compensation) to get the desired color.

Process # 3 - the color of diamond coating on the diamond refers to a thin layer of artificial, which changes the color of the diamond. The coating can be any desired color or cause interference effect of color. Unfortunately, sometimes this process is completed, deceiving the buyer. It is managed by a fairly simple process, it has been around for many years (even if the coating material is much better) and it does not require a lot more high-tech equipment. I recently reviewed some pink diamonds seen on the market, china pearl jewelry, they are very attractive .... and, of course, you have to buy them know they were covered, and to follow your instructions jeweler to manage content and care for diamonds color expansion.

The coating can be applied over the entire surface of diamond, diamond or the bottom of a narrow band around the waist. Correctly apply the coating can change the color of one or more color content. Some coatings can be removed by boiling in acid, or strong detergents or household chemicals. Sometimes dots or larger areas of blue or violet ink to help fight with diamonds painted a yellowish color. Diamond is usually set to cover the points so that they seem to be difficult in a stone up a hill.

Thus, the improvement of diamond color is right for you?

Maybe ... Natural fancy colored diamonds can be beautiful, but they are expensive! expansion of diamond colors are affordable and many people in colored diamonds. Ask your jeweler if they have rhinestones .... either natural diamonds or color expansion. It is always interesting and fun to watch something else!

Under normal wear and colored diamonds irradiated HPHT enhanced bleaching. Just note that if you have done every kind of service to the gem. If this type of diamond color enhanced exposed to excessive heat, can be colored. The jeweler should know that diamond diamonds color expansion, and then decide the best jewelry course of action. colored diamonds enhanced diamonds are now also little attention to the wider use of colorless diamonds. There are a lot of stones more exciting with small diamonds are available in blue, yellow, black or green.

Now you know better about the color of diamonds, and someone tried to sell what they want, as a natural colored diamonds, but at a great price ... You know, something just does not make sense to offer. must accompany the report of the laboratory classification respected, all-natural fancy diamonds that are sold as natural. If you use a reputable company and you have gone through what you are buying peace of mind that you will have the opportunity, something bad happens to fall. As in any situation related to buying something expensive that few people know, education should be part of the plan. This is especially important if you are considering purchasing a diamond color expansion.
