4C’s of Diamonds

What is the 4Cs of Diamonds

The 4Cs of diamonds are Carat, Cut, Clarity and Color. Diamonds are mined from the earth and they come in different shapes, sizes and colors. The four Cs determine how a diamond is graded on a scale of 1 to 10.The cut affects how well light passes through the diamond so it can be seen by human eyes; clarity measures how many blemishes or imperfections there are inside the diamond; color is judged based on hues such as yellow (dun), brown (fancy) or blue (emerald).

Diamonds are the most precious and durable stones in the world. They are so precious that their weight is measured in carats. A carat is the weight of a diamond, which is about 2.75 grams. Many factors go into determining a diamond’s quality, but carat weight and cut are the most important. Essentially, a diamond’s quality is determined by how much waste (or blemishes) it has, as well as its clarity, color, and cut.

Diamonds are cut using some of the most sophisticated equipment in the world. A diamond’s cut affects its appearance, durability, and sparkle. A good cut takes into account the diamond’s size, shape, and symmetry. A poorly cut diamond will appear ugly and may even be too small or too large for its setting. A good cut should also ensure that the diamond is evenly distributed across the diamond, and that there are no gaps or bubbles.

Diamonds are graded on a scale from D (no defects) to Z (extremely small blemishes that do not affect the diamond’s appearance). Diamonds in the lower grades are less expensive, but they may contain more imperfections. diamonds in the higher grades are more expensive, but they are typically of higher quality.

Diamonds come in a variety of colors, ranging from yellow and brown to blue, green, and purple. Some of these colors may be less visible than others, but they are still there. Diamonds with a higher color grade will typically have more visible colors. However, Contrary to popular belief, a diamond’s color doesn’t affect its value. Nor is it affected by the level of light in which it is seen.

CARAT – A diamond carat is the unit that is used to measure the weight of a diamond. The bigger the carat, the rarer will be the diamond.

COLOR – A diamond’s color is rated on an alphabetical scale from D (colorless) to Z (light yellow), with the best and most valuable diamonds being completely colorless.

CLARITY – Diamond clarity is measured on the basis of the presence or absence of inclusions or natural blemishes within a diamond that do not actually affect the beauty of a diamond.

CUT – A high quality diamond cut is what gives a diamond its symmetrical perfection. And it is the symmetrical perfection that highlights a diamond’s maximum radiance.


A diamond carat tells you about the weight of a diamond. Each diamond carat can be further divided into 100 points. So the more the diamond carat weight, the more will be the price of the diamond, with larger diamond being rarer. The history of the diamond carat system can be traced back to early gem traders who used the carob seed as counterweights in their balancing scales.

  • Always consider the diamond carat and cut together, as a cut that is not up to the mark will do nothing to enhance the beauty of a diamond with a larger carat.

Diamond clarity is assessed on the basis of the absence or presence of inclusions or blemishes in a diamond. Where blemishes refer to the surface flaws in a diamond, the inclusions stand for the internal defects within a diamond. So the surface and internal imperfections come together to measure a diamond for its clarity.

These imperfections in a diamond are microscopic in nature, and in no way perturb the beauty of a diamond that is visible through the naked eye. But when it comes to the clarity grades, diamonds that have the least blemishes and inclusions get the highest grades.

As far as the 4C’s of diamonds are concerned, diamond clarity is the least important. This is due to the fact that the blemishes and inclusions in diamonds are so tiny and small that they are only visible under the microscope and not with the naked human eye. Still diamond clarity grades do affect price.

Factors Influencing Diamond Clarity Grades –

There are 5 factors that determine diamond clarity. These are the size of the blemish or inclusion, the number of easily seen inclusions, the position of the blemish, the nature of the flaw, and lastly the color and relief in the diamond.


The cut of a diamond is certainly one of the most important factors that need to be kept in mind while buying a diamond. The cut is what gives any diamond its true value. For, without a high cut grade, even the best quality diamond would look unattractive. A diamond that lacks a proper cut can also appear smaller than it actually is. Hence, it is crucial that you pay full attention to the diamond cut, before actually buying it.
