Understanding the Clarity “C” of Diamonds

diamond calrity

Diamonds are one of the most precious stones on earth. Needless to say, one needs to be very careful and informed while making such a costly purchase. That being said, there are four factors that determine the quality, hence affect the value of a diamond. These four factors are collectively known as the 4 Cs.

The 4 Cs stands for:

  1. Cut
  2. Clarity
  3. Color
  4. Carat weight

This article talks about the second C that is clarity. Diamond clarity refers to the extent to which there are imperfections and blemishes in a particular diamond. A diamond that features major blemishes and inclusions is rated low on the diamond clarity scale. This is because such diamonds have flaws and interruptions that obstruct the path of light when passed through the particular diamond. As a result, this particular diamond will shine less when exposed to light. The location of the inclusion also affects the brilliance of a diamond. Expert diamond cutters go to great lengths to cut a diamond in such a way as to hide the inclusions present on it.

The Gemological Institute of America (GIA) has developed the 11 point diamond clarity scale on the basis of which the clarity of diamonds can be graded. GIA has considered several factors while devising this clarity chart. These include the number, color, size, reflectivity and the location of the inclusion or blemish that can be seen under ten times (10x) magnification.

Following is the GIA’s diamond clarity scale with explanations along with each grade:

FL (Flawless): It implies that the diamonds are absolutely free of any inclusions or blemishes.

IF (Internally Flawless): It means that the diamonds contain no inclusions, but there are certain blemishes that are visible under 10 x magnification.

VVS1, VVS2 (Very, Very Slightly Included): This implies that the diamonds contains some inclusions but they are difficult to be seen under 10 x magnification. The VVS1 inclusions can only be seen from the pavilion, while the VVS2 inclusions can be seen from the crown.

VS1, VS2 (Very Slightly Included): This clarity grade implies that the diamonds have inclusions that can clearly be seen under 10 x magnification, however these inclusions are very insignificant and can be marked as minor.

SI1, SI2 (Slightly Included): This clarity implies that the diamonds have noticeable inclusions that can be easily seen under 10 x magnification. The SI1 flaws are normally undetectable by the naked eye, whereas the SI2 flaws are generally visible to the naked eye.

I1, I2, I3 (Included): This implies that the diamonds contain obvious inclusions that are so major that they can affect the shine, transparency and brilliance of the particular diamond.

Don’t believe anyone when it comes to purchasing diamonds. It is a pricey decision. Stay informed and make your own choice.

What Does the Color of Diamonds Mean?

4 C’s

When experts examine diamonds, they are looking at four different aspects of the gem, called the 4 Cs. These are the color, cut, clarity, and carat of the diamond. The color of diamonds is the element that many laypeople simply do not understand, especially since many people who are looking at two diamonds might not be able to pick up the subtle color differences that an expert can see. The colorless diamonds, also called white diamonds, actually have varying levels of color in them. Diamonds that have a yellowish or brownish tinge to them are not as valuable as the diamonds that are truly clear and colorless.

Color of Diamonds

To determine the color quality of a diamond, the expert needs to look at it before it goes into a piece of jewelry though. When it is in a setting, the metal can actually make a clear diamond look as though it has a slightly different color. When they are in yellow gold, they might appear as though they have a yellow tint although it is just a trick of the light.

Experts will judge the color of the diamond based on a system set up by the Gemological Institute of America, or AGI New York . They have a grading system for diamonds that goes from D to Z. Those diamonds that have a score of D are extremely rare. It means that they are entirely colorless, and these are the most sought after of diamonds. The diamonds that have a Z grade would have a lot of unwanted color in them. Naturally, where the diamond falls in this grade will greatly determine the value of the diamond.

The diamonds rated D, E, and F are colorless. Those rated G, H, I, and J are nearly colorless, and K, L, and M have some color to them.  It is usually slight but yellow. Most of the time, people can’t see the color with the naked eye. Diamonds graded N, O, P, Q, and R have a visible yellow tint to them. S through Z graded diamonds are visible as well, and they are noticeably worse. The diamonds that fall into that category may even take on a brown appearance. You may even be able to see the color difference when the diamond is mounted.

When you are choosing colored diamonds, try to understand What Does Diamond Mean to you? Always inspect the diamond and check the diamond report to see where it falls on this scale.



The Spectrum of Colorful Diamonds

Did you know that diamonds aren’t limited to just the colorless variety? While the colorless diamond is the most common, the jewelry market has seen a marked increase in colorful diamonds. Colored gem stones allow you to give your jewelry an added flair. Since each color represents a different mood, you can pick and choose your daily jewelry selections according to the way you feel that morning. Since diamonds represent luxury and opulence, with the emergence of colors of diamonds it has become easier for the upper crust to customize their jewelry without having to settle for one of the lesser known stones on the market.

Rarity of Color Diamonds

Colored diamonds are incredibly rare. They actually only tend to appear once out of every 10,000 diamonds mined. This rarity is what lends the colored diamond its desirability and hefty price tag.

One of the most sought after colored diamonds is the blue diamond. Recently, a 29.6 carat blue diamond was found in the Cullinan mine near Pretoria in South Africa. Some of the larger blue diamonds have actually sold at a price of over $1 million a carat. Out of the 1 in every 10,000 diamonds that yield a colored diamond, blue diamonds are only found in only a fraction of those.

The rarest of all colorful diamonds, though, is the red diamond. There are probably only 20 red diamonds in all of existence. In this case, if you have your heart set on a red stone, you may want to stick with rubies or garnets. Depending on how deep your pockets go, red diamonds may be out of your price range.

Available Colors

There are several different colors available when picking out your diamond, although you might be surprised to learn what actually causes each one.

Nitrogen is one of the most common elements found in diamonds and has the ability to turn them yellow and brown. Brown diamonds have seen a sudden boost in popularity thanks to them being marketed as chocolate diamonds. Blue diamonds are created when boron is introduced to the gems while green diamonds are created by irradiation by alpha particles. Plastic deformation is also responsible for turning diamonds brown, pink, and red. The popular black diamond isn’t actually black. Instead it is just full of dark inclusions that give it the appearance of being black.

The truth is, even though colorful diamonds are incredibly expensive because of their rarity, the reason they have their colors is due to impurities and defects. This is probably the only time a defect will actually make you pay more for an item rather than less. No matter how they got that way, fancy color diamonds are a unique way to add a pop of color to your fine jewelry without having to sacrifice quality. Just be sure to have their quality verified before committing to a purchase. You wouldn’t want to spend tens of thousands on a stone only to find out later that it was one of the lesser quality gems instead.
