The Manufacturing Process – Cutting And Polishing The Diamond To Perfection

You see a piece of jewelry with diamonds embedded in it. You’re instantly drawn towards its magnificence of beauty. You see, diamond is the standard of perfection and brilliance simultaneously. 

It takes more than just finding the piece of carbon to give the value you see in it. To bring out the best, a diamond has to go through an elaborate manufacturing process involving cutting and polishing. 

If you want to be a passenger in the journey of a diamond turning into a forever gem, don’t just stop here! 

How is Your Precious Diamond Manufactured? 

The sparkle of a diamond depends strongly upon how it is manufactured, i.e., cut and polished into a finished gem. Do you know how people generally refer to a phase of gruel and hustle as the defining moments? Diamond is the inspiration behind such quotes and phrases. 

You have to rough up a diamond to turn it into a stunning piece of gem presented to the world. To bring out the elegance of a diamond, it has to go through five phases of manufacturing. 

  • Planning: In a world where a diamond is the hallmark of memorable moments, precision is the key to cutting the rough diamonds. It is the essential step in determining the size and numbers a rough diamond will produce. The size, clarity, and crystal direction are the proper standards for marking the diamonds correctly. The slightest error can cause thousands of dollars of loss. 
  • Sawing: After meticulously marking the diamond, it has to be cleaved into different shapes and sizes. This step is crucial in the diamond cutting and polishing process for the glimmer that the crystal produces. Interestingly, cutting the diamond requires the diamond itself. 

Yes, you read that right! To get an excellent polish diamond, sawing it where it is marked makes the cut. To ensure the finesse in cutting, the diamond powder covers the copper blade, and only then do you cleave the marked diamond. 

  • Bruting: Even the most rigid material on the planet needs soft touches to convert into an excellent polish diamond. This is where bruting comes into the picture. Bruting is used in the diamond cutting and polishing process to give the rough edges around the structure for drawing facets on it. 

Don’t worry about the name. It’s done using a lathe and another diamond. The diamond to be bruted is fixed on a lathe, and the other diamond forces itself along the edges. Gradually, one diamond supports another in becoming more rounded! 

  • Blocking: You’ve created rough pieces of the diamonds; now what? Your diamond is as good as the light that its facets can reflect. Blocking is the additional step you should closely observe and adapt to make these facets or faces of the diamonds. 

Not only this step in the diamond cutting polishing process will ensure the light reflection, but also the symmetry of your precious gem. You should know the size of the rock you want before polishing the diamonds. During this step, for small diamonds, you’d need 17-18 facets. When a larger diamond is being manufactured, the light that enters the crystal has to have a broader area to bring fire to the gem. This is why you add more facets to the giant crystal.

  • Polishing: You know what is more challenging than finding the splendid diamond crystal on the planet? It is polishing the diamonds while keeping intact their clarity and beauty! The difference between an excellent polish diamond and a diamond stone is in its symmetry. The symmetry is achieved by blocking the faces in the proper proportions. 

Right after blocking, it’s time for brillianteering the crystal. A brilliant is a diamond polisher who adapts the facets into perfection for its brilliance and worth. You ultrafine the shaping of the gem to give it a mirror-like surface while brillianteering or polishing. You can use diamond polishers such as fine grades of diamonds and polishing agents like metal oxides.

Polishing the diamonds is the finest of the expertise in the entire process. A minor inconsistency can devoid the world of having an extraordinary love story starting with a diamond ring. Such a tragedy that can be!

To Sum Up

The manufacturing process of a perfect diamond is as intriguing as the diamond itself. The sheer worth of the diamond can be valued differently only based on the diamond cutting, and polishing process is a mark of its importance. 

The miniature system of mirrors is capable of bringing fire to the moments of your life. The splendor of the gem is created through the efficiency of the manufacturing process. Whether it is about a family heirloom or a carefully purchased engagement ring, a diamond symbolizes longevity and brilliance. Your skillfully cut and polished diamond will be a reminder of the same!

Diamond Color Vs. Clarity – Which Is More Important?

Diamong Birth vs. Color

If you’re at the store to buy a diamond for the very first time, you’d probably run by some research. You may be fixed on a particular shape of diamond or know well about the settings you’d want on your diamond. In fact, you might be fixated on the color vs. clarity round diamond dilemma when you are into it.

Provided that you’ve done your homework pretty extensively, you’d know that diamonds are graded based on clarity, color, cut, and carat. But often, people get confused between diamond clarity and color

In simple words, color is the absence of color, and clarity is the absence of imperfections. We’ll take you through a guide to diamond color and clarity to give you a better knowledge of their distinction. So, which is more important, between clarity vs. color of a diamond? Let’s find out.

Are Diamonds Cut by Hand or Machine?

Cutting a diamond and transforming it from a  rough stone into a faceted gem is an art. It requires specialized knowledge, tools, and equipment to do justice to this difficult workpiece of art. Cutting a diamond into its perfect shape and polishing it requires efficiency.

Did you know that the first diamond cutter and polisher guild, known as diamantaire, was invented in Nuremberg, Germany? It was this diamond cutter and policher founded in 1375 that gave rise to the different cut types.

The first cut types were oval, square, and so on. This was followed by specific qualities of cutting within the shape which influenced the quality and price of the diamond. Since diamonds are special stones, they require special diamond-coated surfaces to carve out the diamond.

Diamonds are cut using both hands and machines. A rough diamond is cut by a highly trained cutter or they use a machine for the cutting process. Although technology has highly advanced and there are highly accurate machines to cut out the diamonds, diamond cutting using hands is a piece of craftwork.

Diamond Cutting

Diamond cutting requires cleaning it using a steel blade or laser. The stone is then placed in wax or cement mold to hold it stable and cleave it along the tetrahedral plane which is its weakest point. Additionally, sawing is used in the absence of any weak points. However, with newer technology available, cutting diamonds is becoming easier over time.

Once the stone is cut in the appropriate form, it needs to be bruted or girdled. Having it completely smoothened out into a round shape, it’s time to polish the diamond to give it its shine.

Diamond Polishing

After cutting and smoothening the diamond, it is time to derive the faceted gem out of the diamond it is destined for. The rough of the diamond is placed on the rotating arms to polish the same using a spinning wheel.

This smoothens the diamond and reflects its facets. Additionally, polishing is well processed through the stages of blocking and brilliant. This is where the fine-tuning with diamond clarity and color hop in. 

Color Vs. Clarity in Diamonds: What Affects Diamond Brilliance More?

Brilliance comes from all the characteristics of a diamond when each is perfectly defined. The intensity is based on the stone’s cut. Diamond color and clarity do not directly define the brilliance of a diamond. However, they play a major role in making a diamond perfect and complete with its visual effects.


Indeed, diamond color does not directly affect its brilliance. However, colorless diamond stones appear much brighter and livelier overall. On the contrary, diamonds with a strong yellow tint are low-grade stones that appear darker and are concluded to be less brilliant.


In terms of clarity, it is quite common to believe a stone with fewer flaws or an absolute absence of flaws to be sparkling clean. Visual imperfections might make a diamond appear dirty. However, such imperfections do not change the reflection of the light on the stone. Thus, its brilliance is preserved.

Any diamond’s brilliance will be affected if it has several negative and large inclusions. However, most jewelers do not store such diamonds that are low in clarity.

A diamond’s brilliance could be negatively affected by stones with numerous, very large inclusions, but most jewelers do not carry diamonds of such low clarity.

How Does Color Affect the Appearance of a Diamond?

According to Pricescope Diamond Forum, diamonds’ GIA and AGS certification grades are based on diamond color and clarity chart. The GIA certification takes into account the diamond color based on a letter scale. 

On this scale, D is the top grade. It symbolizes that the diamond is indeed colorless. The lower it is graded on the chart, the more it appears to be tinted. A K grade or a grade lower than that on the GIA grading chart means that the diamond is slightly tinted with yellow color.

You will find that the yellow tint becomes more and more prominent when you go down the grading chart to check for its color.

How Does Clarity Affect the Appearance of a Diamond?

Diamond clarity refers to the number of inclusions or internal flaws along with the number of imperfections put into a diamond. You must know that clarity in diamonds also refers to the surface imperfections of diamonds. These imperfections are visible when the diamond is placed under a magnification lens.

FL is the highest grade in terms of flawlessness. It means that the stones do not have any internal flaws even when checked in 10X loupe. If you are looking at a lowly graded stone, you may expect to see more imperfections, such as black spots or lines inside the stone.

Diamond Color and Clarity Guide: How to Choose Diamond Color and Clarity?

When buying a diamond, it is important to ensure that the stone is eye-clean. This means that it should not have any flaws that are visible to the naked eye. You need not aim for the highest-clarity stone. 

This is because VS1-VS2 or SI1 graded diamonds appear as clean as FL or IF-rated clarity stones. You will only have such knowledge if you invest enough time to learn what color and clarity are good for diamonds. 

If you aim to buy a round diamond for a yellow gold setting, a grade as low as J, K, or L, even M, sounds good. You need not worry about the visibility of yellow tints as they set the stone. However, other diamond cuts may require looking for higher grades of color such as I, J, or K.

Round diamonds are best suited with platinum or white gold settings. It would not be wise to go below the grades of H, I, or J colors. If you are aiming for cuts other than round, G or H would be a better choice. Avoid lowering the grade than I color whatsoever.


While buying a diamond, the diamond color and clarity are equally important to judge the perfect stone. Both equally impact the brilliance of a diamond, though not directly. You should, however, stand at a balance of the two when you make a choice.

All you need to do is opt for a diamond that is eye-clean without any visible yellow tint. Once you go through the point of finding the appropriate clarity and color grade for your diamond, you’d have to shift the focus to the cut and carat of the stone. And you shall have the perfect stone decorated on your hand or whatsoever.
