Behind the Sparkle: How Are Diamonds Cut?

Transforming rough stones into breathtaking symbols of luxury, a diamond cutter plays a pivotal role in unlocking the true potential of every gem. This article will unravel the precise techniques and advanced technology employed in diamond cutting, revealing the intricate process that shapes, polishes, and perfects each diamond.

As we delve into the secrets behind the sparkle, you’ll gain a newfound appreciation for the remarkable journey each diamond undergoes from a rough crystal to a dazzling masterpiece, all under the expert guidance of a skilled diamond cutter.

Are Diamonds Cut By Hand or Machine?

Diamonds can be cut both by hand and by machine, depending on the level of precision and efficiency required. Traditional diamond cutting, often performed by skilled artisans known as diamond cutters, involves the use of hand tools like a diamond cleaver and a saw. These experts meticulously study the diamond’s characteristics and plan the cuts to maximize its brilliance and sparkle. 

On the other hand, modern technology has introduced automated diamond cutting machines that use computer algorithms and lasers to precisely cut and shape diamonds. These machines can achieve consistent and highly accurate results, making them ideal for mass production and maintaining strict standards in the diamond industry. While hand cutting preserves the artistry and personal touch of the craft, machine cutting has become increasingly prevalent in the pursuit of precision and efficiency in the diamond cutting process.

The Diamond Cutting Process

Diamond cutting is a meticulous and skilled craft that transforms rough, uncut diamonds into exquisite gems that adorn jewelry pieces worldwide. The process involves several intricate steps, each executed with precision to maximize a diamond’s brilliance, fire, and overall beauty. Here’s a glimpse into the diamond cutting process:

Planning and Evaluation

The process begins with the careful evaluation of the rough diamond. Diamond cutters assess the stone’s shape, size, and inclusions to determine the best way to cut it to maximize its value and beauty. Cutting decisions are crucial, as they will affect the final appearance of the diamond.

Cleaving or Sawing

In this step, the diamond may be cleaved or sawed to create smaller pieces, known as “diamond rough.” Cleaving involves using a sharp tool to split the diamond along its natural planes, while sawing uses a diamond-coated blade. This initial division is essential to create manageable pieces for further shaping.


Once the diamond rough is obtained, the next step is bruting. In bruting, the diamond is shaped into a round form by rotating it against another diamond. This process creates the diamond’s basic shape and prepares it for the faceting process.


Faceting is one of the most intricate steps in diamond cutting. It involves cutting and polishing the diamond’s facets, which are small, flat, polished surfaces that interact with light to create the diamond’s brilliance. Skilled diamond cutters use precision tools to create a specific number of facets in various shapes and angles, including the table, crown, girdle, and pavilion.

Inspection and Quality Control

Throughout the cutting process, the diamond is frequently inspected to ensure that each facet is precisely cut and polished to perfection. Quality control measures are crucial to achieve the desired brilliance and sparkle in the final product.

Final Polishing

In the final polishing step, the diamond is given its ultimate shine. Diamond cutters use a polishing wheel coated with diamond dust or powder to remove any remaining imperfections and enhance the diamond’s luster.


After the diamond has been cut and polished to its final form, it undergoes a grading and certification process by reputable gemological laboratories. This crucial step provides detailed information about the diamond’s cut, color, clarity, and carat weight, helping consumers make informed purchasing decisions. The diamond grading process ensures that the gem’s quality is accurately assessed and documented, giving buyers confidence in the authenticity and value of their chosen diamond.

Cost of Diamond Cutting

Diamond cutting is a highly specialized and labor-intensive process that requires exceptional skill and precision. Diamond cutters are trained professionals who meticulously shape and facet the rough diamond to enhance its brilliance and beauty. The cost of diamond cutting depends on various factors, including the size, shape, and quality of the diamond, as well as the complexity of the desired cut. Larger and more valuable diamonds often incur higher cutting costs due to the care and precision required to maximize their potential. Additionally, the cutting process can result in some material loss, further affecting the cost. 

Why Is Diamond So Hard To Cut?

Diamond is exceptionally hard to cut due to its remarkable hardness and durability. In fact, diamond is the hardest natural material known to humankind, scoring a perfect 10 on the Mohs scale of mineral hardness. This unparalleled hardness arises from the strong covalent bonds that hold its carbon atoms together in a crystal lattice structure. When attempting to cut or shape a diamond, traditional tools and materials like metal or other gems are ineffective. Instead, diamond cutters rely on other diamonds, which are the only materials that can scratch or cut through diamond. The process involves precision and skill, as well as the use of diamond saws, laser cutting, or other specialized techniques. This inherent hardness is precisely what makes diamonds so prized for their durability in jewelry, but it also makes them a challenging material to work with, requiring expertise and the right tools to bring out their exquisite beauty.

Where to Get Diamonds Cut

The best places to get diamonds cut are typically reputable jewelry stores or specialized diamond cutting workshops. Many well-established jewelers have in-house experts who are trained in the art of diamond cutting and can provide you with guidance and options for enhancing your diamond’s brilliance. Additionally, these jewelers often offer diamond grading services, which are crucial for assessing the quality of your diamond post-cutting.

Certified gemologists and diamond cutters, who offer their services independently or through respected gemological associations, are also excellent resources. These professionals not only excel in diamond cutting but also provide comprehensive grading reports, ensuring that your diamond’s cut maximizes its beauty and value. By choosing a reputable source for both cutting and grading, you can ensure that your diamond receives the care and expertise it deserves.
