Diamond jewelry, as some would put it, is the royalty among all gems. As such, assessing the value and quality of this gemstone had been refined to almost an exact science and a very fine art for hundreds of years now.

Today, dealing in diamonds either as an ardent admirer (wearing one) or as an astute trader of the same, one would need to be familiar with the four Cs – color, cut, clarity and carat.

Color

With the naked eye, most diamonds would appear colorless, but they do have subtle shades of colors. Experts use the letter D (colorless) moving through all the letters all the way to Z (light yellow) in identifying them.

A colorless diamond is chemically pure and structurally perfect. It lets through most of the light (perfectly transparent) and produces the most amount of brilliance.

Most natural diamonds, however, are imperfect, and colorless diamonds are very rare.

It is, therefore, the most expensive of all.

The diamond color is produced by chemical impurities or structural defects in the stone’s crystal pattern. It causes a yellowish to brownish tint. However, blue or pink diamonds are also considered more desirable and command some very high prices as well.

Gemologists label diamonds with unusual or intense colors as “fancy” and they have their own rating systems, although it is not commonly used because of the relative rarity of such stones.

Cut

This is the most important of all the four Cs in assessing the stone’s beauty. Cut refers to the precise proportion and dimensions of a finished diamond. This is not to be confused with the stone’s shape (round, princess, marquise, pear, baguette, etc).

A diamond that had been cut properly allows light to enter and refract it, creating what is called brilliance. Cut too shallow or too deep, a stone will not properly refract the light and will look dull and lifeless.

A well-cut stone looks like it has greater carat weight, has more clarity and color. All in all, it appears to be of better grade than it actually is.

Clarity

Diamonds have natural imperfections called inclusions. These are minerals or crystals trapped inside the stone, and they determine the clarity of the stone.

Nearly all stones have characteristic inclusions (“birthmarks”) which make them unique and identifiable. These imperfections are graded accordingly and these also determine their value.

These are noted in the stone’s certificate from IF (internally flawless), VVS (very, very slight inclusions) all the way down to “visible inclusions”(I).

Carat

This is the measurement of a diamond’s weight. One carat is 200 milligrams. The point unit (0.01 carat or 2 milligrams) is used on stones lesser than one carat.

Normally, the price per carat increases with carat weight because larger diamonds are rarer and desired. However, carat weights are not the final arbiter of value.

A smaller stone with better color and clarity commands a better price than a bigger one with poor color and clarity. Total carat weight (TCW) is used when referring to the total mass of stones in a piece of jewelry (bracelets, necklaces, earrings, multiple-stoned rings, etc.)

Your choice

Choosing the diamond jewelry of your dreams actually boils down on your attraction to a particular stone, maybe because of its color, brilliance or its shape. Knowing the four Cs is important, whether you are a layman or want to be an expert.

Some people said that yellow diamond ring is not worth to buy; some others said that colorless or other fancy colored diamonds are better. But, it’s that true? I don’t think so.

Sometimes, people have misperception about what is the meaning of yellow diamond. If you already learn about diamond 4C’s, you must be know that for a white diamond grading, there are color grading ranging from D (colorless white) to Z (light yellow). Yellow diamond is not a grade Z of white diamond grading, but it’s beyond that. That is why they called fancy colored diamonds.

Yellow diamond ring price could be more expensive than colorless white diamond. Yellow diamond gained its popularity several years ago when many celebrities give yellow diamond ring to his fiancée as an engagement ring.

Deep color natural diamonds are rare and therefore they are so expensive. While there are many pale color yellow diamonds, these diamonds are prized not so expensive and sometimes they categorizes as a white diamond grade Z color.

However, there are also manmade yellow diamonds. These diamonds are produced in laboratory. CVD (chemical vapor deposition) is the name of process to produce a synthetic diamond. With this process, people try to simulate the diamond forming process in the labs as in nature, of course, it’s much faster, and you don’t have to wait million years to get the diamonds.

Synthetic diamond qualities are getting better and better. So, if you want to buy yellow diamond ring with natural diamonds on it, you better buy the one that have certificate. Without diamond certificate, a normal person could be hard to telling the different between the real one with the synthetic.
