Diamonds have fascinated humanity for centuries, renowned for their timeless beauty, rarity, and brilliance. As one of the most coveted gemstones in the world, they carry with them not just inherent value, but the labor and expertise of those who transform rough stones into dazzling masterpieces. At Eternity Gems, we are proud to be at the forefront of this process, specializing in the manufacturing of larger rough diamonds and facilitating trades for polished diamonds. But what makes the journey from rough to polished so unique? It’s a delicate blend of art, science, and precision that we continue to perfect every day.
The Diamond Cutting Process: Where Art Meets Precision
The diamond cutting process is both an art and a science. At Eternity Gems, we recognize that the transformation of rough diamonds into beautifully polished stones requires a deep understanding of both the gemstone’s natural properties and the tools required to unlock its full potential.
-
Planning and Design: The first step in diamond cutting begins long before any cutting tools are put to work. At Eternity Gems, our experienced gemologists begin by evaluating the rough diamond’s size, shape, and structure. This planning stage is crucial as it determines how the stone will be shaped to maximize its brilliance while minimizing any loss of material. For larger rough diamonds, this planning stage is even more significant, as it involves intricate calculations to ensure the diamond’s optimal value.
-
Cleaving and Sawing: Once the design is finalized, the diamond undergoes cleaving or sawing. Cleaving is a process where the rough diamond is split along its natural grain using a special tool to make precise cuts. For larger stones, sawing may be used, where a laser or circular saw creates clean, straight cuts. This is a critical phase in the diamond cutting process as improper cutting could lead to flaws or diminish the diamond’s overall quality.
-
Shaping and Bruting: After the rough diamond is divided into smaller, manageable pieces, the next step is shaping. This is where the true artistry begins. The diamond is placed into a machine that uses a rotating wheel or a grinding tool to slowly shape the stone. For larger diamonds, this step requires careful precision to preserve as much of the rough diamond’s natural beauty and weight as possible.
-
Faceting: Faceting is what truly brings the diamond to life. Each facet of the diamond is carefully cut and polished to reflect light, creating that signature sparkle that diamonds are known for. This requires an expert’s hand, as the angles and proportions of each facet play a key role in how light travels through the stone. The brilliance of a diamond depends on how well the facets are cut, making this one of the most delicate stages in the process.
-
Polishing: After the faceting is complete, the diamond is polished to perfection. This final step ensures that the facets reflect light evenly, creating the stunning shine that diamonds are famous for. Polishing is a meticulous process that requires a combination of specialized tools and an expert’s keen eye for detail.

The Science Behind Diamond Cutting
The art of cutting a diamond is supported by years of scientific research and technological advancements. At Eternity Gems, we utilize cutting-edge technology to assist in every stage of the process, from laser sawing to precision faceting machines. These innovations help ensure that every diamond meets our exacting standards of excellence.
Optical Performance: The science behind a diamond’s optical performance is fundamental to its value. Factors such as light dispersion, refraction, and the diamond’s cut grade all come into play when assessing its overall quality. The ideal cut is designed to reflect light perfectly, creating the brilliance and fire that make diamonds so captivating. As a leader in the diamond manufacturing industry, Eternity Gems uses advanced tools to analyze these elements and ensure each stone’s optical properties are optimized.
Technology and Innovation: The introduction of lasers and computer-assisted design software has revolutionized the diamond cutting industry. These technologies allow us to make even the smallest adjustments with precision, leading to a higher quality product. For larger rough diamonds, advanced mapping software helps our craftsmen determine the best cutting approach, minimizing waste and maximizing the stone’s value.
