Overall Diamond Advice

The overall look of the diamond consists of a balance and combination of the 4 Cs. The 4cs of a diamond refers to the cut, carat, color and clarity of the diamond. Although all the 4cs of a diamond are equally important in the quality of the diamond, the cut is the most important. The cut has the biggest effect on the excellence and appearance of the diamond. A 1.5 carat round brilliant (I color, SI1 clarity) and a 9 carat round brilliant (K color, VS2 clarity) are examples of diamonds that can look beautiful with the correct cut. It’s still important to combine the perfect cut, clarity and the perfect balance in color to ultimately pick the best diamond if you want to invest your money wisely. Are you having trouble evaluating your diamond’s quality or price? Why not get into contact with a professional evaluator to help you? They’ll be able to give you the necessary assistance.

Understanding The 4cs Of Diamonds Chart

Diamonds are defined by four elements. These four elements, also known as the 4 Cs, give diamonds their shape and fascinating appearance. The 4 Cs are better known as the cut, color, clarity and carat of the diamond. The 4 Cs are a perfect equilibrium of features and elements a diamond consists of & it’s what we appreciate when we look at the stone. The 4 Cs can be separately graded and evaluated to determine the quality of the diamond. Grading of quality is done on a scale and terms are used universally. Different grading results may be concluded according to lab entity. The GIA and the AGS are two main trustworthy entities recommended when you want a certificate for your diamond. The standard and worth of a diamond are measured by the grading results of the 4 Cs. The value of a diamond varies according to the grading of the specific stone. Although two diamonds might look the same, they might be different in grading. If you know the principals of these grading, you’ll be able to identify the better diamond easier. In the end you still want to select a diamond that’ll be a showstopper and that’ll demand attention. Comprehending the 4 Cs are crucial when you’re buying diamonds.


Have you ever wondered why some diamonds sparkle more than others? The answer is simple—it’s all in the cut.

There are different components considered when referring to the cut of the diamond:

  • Comparative relations
  • Symmetrical angles
  • Shining ability
  • Luminosity
  • Overall complexity
  • Dispersion
Diamonds are graded by entities such as the GIA into different scales from high quality to low quality:
  • Ideal
  • Excellent
  • Very good
  • Good
  • Fair
  • Poor

Diamonds that are cut in a way to show the best balance between the dispersion and the brilliance will fall into the Ideal and Excellent grades. The shape of the diamond will also be considered when characterizing the diamond according to grades. There are many different cuts in diamonds. Diamond cutters also cut diamonds differently and according to what their aim is when cutting. If a diamond has inclusions, a diamond cutter might want to reduce the overall inclusions by cutting the diamond. This might result in a matter or duller appearance. The backscattering of light might also be less in a deeper cut diamond. Diamond cutters often cut deeper diamond shapes when they’re aiming to increase the carat’s weight. Always make sure you look at the cut of a diamond above all the other Cs. Selecting a seemingly perfect 2 carat diamond that fits all the basic C criteria but doesn’t have the best cut can look drab. An example of a diamond that’s not as shiny as it could be just because of the way it’s cut, is a 1.50 carat round brilliant. Always make sure you know what the terminology really means. Buying a diamond advertised as excellent doesn’t guarantee the best diamond cut. Most diamonds are advertised as excellent cuts. Some of these are truly excellent in the sense of the word such as a 1.5 carat round brilliant whilst others lack shine and fire. The most beautiful diamonds consist of the best cut. It’s worth consulting a professional to help you select the best cut if you’re unsure or hesitant.

Carat Weight

The size of a diamond doesn’t determine the carat weight. The carat weight can be heavier in a smaller stone than a bigger stone. You can also get two of the same carat stones that have different carat weights. The weight of a 1 carat diamond is 0,2 grams. The carat weight is an important factor when you’re selecting a diamond but always remember to make the sparkle & overall aesthetic look of the diamond an important priority. You want your diamond to shine bright and look beautiful in the end.


The color in diamonds are graded according to how white or yellow the diamond is. Diamonds are graded from D to Z by the GIA. Z is the grade given to diamonds with a yellow, brownish tint. D is allocated to the whitest diamonds. You won’t necessarily be able to see the difference between a yellow toned diamond and a white diamond. It’s therefore recommended to consult a professional when buying a stone. The price tag on diamonds vary greatly according to the grading of the color. Consulting an expert will minimize your risk of paying too much for an unnoticeable yellowish diamond. Your main priority when looking at the color is to aim for a colorless diamond in proportion to the setting. There should also be no interference with the mirroring of light on the gem. Some diamonds are more radiant than others such as the I color diamond. A K color diamond in a cushion cut is a good example of a less sparkly diamond. Always keep in mind that the color of the diamond doesn’t create the sparkle in diamonds. It might emphasize the brilliance but it’s the cut that determines the ultimate dazzle. It’s important to remember colored stones such as green diamonds aren’t the same as white ones mentioned above. Grading of these diamonds are done differently.


Clarity grading evaluates the amount of imperfections and formations a diamond has. The cleaner and clearer from imperfections, the better the grade.

The GIA grades clarity as follows, F being the best grade:

  • Inclusions 2 (I2)
  • Inclusions 1 (I1)
  • Slightly included 2 (SI2)
  • Slightly included 1 (SI1)
  • Very slightly included 2 (VS2)
  • Very slightly included 1 (VS1)
  • Very, very slightly induced 2 (VVS2)
  • Very, very slightly induced 1 (VVS1)
  • Internally flawed (IF)
  • Flawless (F)

Blemishes can prohibit the light reflecting from the diamond. The position, size and shade of imperfections determine the severity in loss of brilliance. We recommend selecting a gem that’s clear to the naked eye. Also focus on the reflection of the diamond, there should be no interferences with the casting back of light. Don’t just rely on your eyes and a certificate to determine clarity. A professional can help you make an informed selection. How the Four Cs Complement Each Other You can’t see just one component with the naked eye when you’re looking at a diamond. Diamonds are a combination of all four Cs. Each component adds to their beauty. It’s fundamental to look attentively at the different ways the 4 Cs influence each other.

Which C in Diamonds Are Considered the Most Important out of the 4cs of a diamond?

  • Cut: The cut is the most important component of a diamond.It’s worth spending more money on the perfect cut than on the perfect color.The exquisiteness of a stone is mostly determined by the cut.Look for a perfect balance in sparkle and fire.
  • Color: Color comes in secondly on the list of important Cs.Look for a white diamond without any discoloration or reflective distractions.
  • Clarity: Clarity is the third most important aspect. The fire and brilliance of a diamond should be the focal point. Select a clean diamond without any imperfections or formations.
  • Carat: The least important of the four is the carat weight.A sparkly diamond will be worth more to you than a higher carat weight.Rather pay less for the carat and more for the cut or color.

The 4cs of a diamond are a great guideline to purchasing diamonds but remember these gems are more than just four components—they all work together to form one beautiful stone. A diamond is a lifelong investment. Do your research before selecting your dazzling stone. Experts can help you with advice on evaluation of diamonds and purchasing the ones you can afford.
