Diamond comes in many different shapes, colors, sizes, and cuts. Each diamond has a unique spark and charms. But have you ever wondered how exactly this diamond comes into particular shapes and cuts? After the process of diamond mining, the very next step is diamond cutting. There are several diamond cutting techniques and methods that are used. These methods somehow enhance the value and beauty of diamonds. Here in this blog, we will explore what is diamond cutting, and how they are cut. Furthermore, we will explore traditional diamond cutting and modern diamond cutting methods.
Before diving into what is diamond cutting and how it is done. We will first find out what is rough diamonds.
The transformation of rough diamonds into shining and sparkling diamonds is really fascinating. A rough diamond is a diamond that is yet to be cut or processed. They come in various natural shapes; octahedral (eight-sided bipyramid), cubic, and triangular (most commonly macles). Cutting down such hard rough diamonds needs great skills. Due to the extremely hard material, diamond cutting requires experts, specific tools, methods, and techniques.
Over the decades the evolution of diamond cutting has always been inspiring. By adapting computer-imaging techniques, precision measurement systems, lasers, and other modern technological equipment, diamond manufacturers have improved their ability to cut gem diamonds in ways unimaginable before.

The process of cleaving is to segregate the rough diamond pieces into separate pieces, to be finished as separate gems. Usually, in the planning stage, diamond manufacturers make and use planes to decide how to split the diamond. Throughout history, cleaving involves splitting the diamonds along their natural planes using a sharp blade. This technique dates back centuries and is crucial for dividing rough diamonds into smaller pieces for further processing.
Cleaving- Traditional Diamond Cutting Method
Sawing is the process where many times, diamonds have to be cut where there is no plane of weakness, which cannot be done with cleaving. Instead, the cutter saws the diamond using a phosphor-bronze blade rotating at about 15,000 rpm. Even though the cutter uses a diamond to cut the diamond, the sawing process can take hours to complete due to the hardness of the material. Yes, it takes that many hours because a diamond is that hard!

Laser cutting has truly changed the world of diamond cutting. It brought a level of precision and efficiency that was hard to imagine. Laser-cutting technology uses focused beams of light to cut through the diamond with incredible accuracy. It is not like traditional methods that may result in more waste or less precise cuts. Laser cutting allows diamond cutters to create hard designs with ease. The precision of laser cutting means that every cut can be made exactly as planned, down to the smallest detail. This method also enhances the beauty and uniqueness of each diamond cost-effectively.

Bruting is considered an essential modern method of diamond cutting. The primary use of this method is to shape a diamond into a round form. Bruting is a really helpful process in creating round brilliant cuts. Bruting can be done by grinding two diamonds against each other. The diamond cutter carefully grinds the edges of the diamond, slowly shaping it into a perfect circle. This step requires a lot of skill and patience. The precision of bruting ensures that each diamond facet is aligned correctly, allowing the light to reflect and bend beautifully.

Polishing is the final and perhaps the most important step in the diamond cutting process. It involves carefully smoothing and refining each diamond facet to achieve maximum brilliance and sparkle. This process is divided into multiple stages, where finer sharps are used to polish the diamond’s surface for perfection. The first stage of polishing is to remove roughness from the diamond’s surface with coarser abrasives. The goal is to achieve a flawless and mirror-like finish. Polishing not only enhances the diamond's aesthetic appeal but also maximizes its value, making it a crucial step in the diamond cutting process.
Diamond Polishing- Modern Method
CNC stands for Computer Numerical Control. CNC diamond cutting merges with computer technology to perform hard & complex cuts with precision. This method is particularly beneficial for creating complex and customized diamond shapes. CNC offers greater flexibility and accuracy.
Fancy cuts include unique shapes like princess, emerald, and heart cuts. These specialized techniques require a deep understanding of the diamond's properties and precise planning. To ensure the desired shape and brilliance are achieved this technique is used. Fancy cuts often pose challenges but result in stunning, individualized gems.
Over the years, there has been continuous innovation in diamond cutting technology and machinery. They have significantly impacted the efficiency and precision of diamond cuts. All the advanced technologies, we have discussed above, have enabled diamond manufacturers to create more flawless pieces. Due to this, there has been an enhancement in the overall quality and value of the gems.
Several factors play an important role in determining the choice of diamond cutting techniques. The type and the quality of the rough diamond are paramount. Different rough stones require specific methods to maximize their potential. The desired final product, including its shape, size, and brilliance, also heavily influences the cutting approach.
Additionally, market trends and consumer preferences impact the decision-making process. Cutters aim to create diamonds that meet current demand and aesthetic standards. Each of these factors contributes to the intricate art and science of diamond cutting. This will ensure the creation of marvelous and valuable gemstones.
As seen above, diamond cutting is both an art and a science. It requires extensive training and expertise. Diamond cutters must possess a sharp eye for detail and a deep understanding of the material's properties. The combination of technical skills and artistic vision allows them to transform rough diamonds into stunning, valuable gems.
In conclusion, diamond cutting is a crucial step in the journey from rough stone to dazzling gem. Traditional techniques like cleaving and sawing have covered the way for modern methods such as laser cutting and CNC technology. The continuous advancements in diamond cutting tools and machinery have significantly enhanced the quality and precision of diamond cuts. As the industry evolves, we can expect even more innovative techniques to emerge, further elevating the beauty and value of diamonds.
