From Rough to Radiance
A Comprehensive Guide to Diamond Processing

Diamonds, one of the world’s most sought-after gemstones, start their journey as unrefined rough stones found deep within the Earth. To transform these rough diamonds into the sparkling, polished jewels we admire, a meticulously engineered process must be followed. This process of transforming a rough diamond into a polished gem involves precision, advanced machinery, and innovation in technology. At STPL, we pride ourselves on providing world-class, cutting-edge solutions that make diamond processing not only efficient but also exceptionally accurate. With technologies ranging from diamond planning machines to robotic diamond shaping and polishing, STPL plays a key role in ensuring each diamond reaches its true potential.

Diamond Planning: The Blueprint for Precision

The first step in the diamond processing journey is planning. Planning ensures that maximum value is derived from each rough diamond while minimizing waste. This phase involves determining how the rough diamond should be cut, keeping in mind the 4Cs: carat, color, clarity, and cut. For this step, STPL offers its industry-leading Magnus Digital Neo, an advanced diamond planning machine that uses superior algorithms to analyze the rough diamond and create a precise cutting strategy. The machine evaluates the inclusion positions and 4C parameters, providing multiple planning options for both round and fancy shapes.

This step is crucial because the plan dictates how the diamond will be cut and polished later. Magnus Digital Neo helps maximize yield and guarantees optimum polish value by leveraging powerful data analysis, ensuring that every rough stone reaches its full potential without unnecessary loss of weight.

Diamond Sawing: Precision Cutting with Advanced Technology

Once the diamond has been planned, the next step is the cutting or sawing process. Cutting is where the rough diamond is divided into smaller pieces based on the plan, ensuring each fragment can be shaped and polished into the final product. The precision of this process is critical, as any miscalculation or uneven cut could lead to significant losses in value and quality.

STPL’s LAZER AIM takes diamond sawing to new heights by combining Advanced Optowave Diode laser technology, ensuring unparalleled precision and accuracy. LAZER AIM can cut through rough diamonds with minimal breakage, which is a common issue in traditional sawing processes. Equipped with features like multipie sawing and automated processes, this machine minimizes the risk of human error and increases efficiency. LAZER AIM’s ability to perform multiple tasks in one go makes it the perfect choice for cutting rough diamonds into smaller, well-defined pieces ready for shaping.

Furthermore, STPL’s MagikCut is a revolutionary technology that minimizes diamond breakage during the sawing process. With advanced multipie sawing in a single operation, it drastically reduces waste and increases yield, ensuring that each diamond retains its value while being cut with precision.

Diamond Shaping: Crafting the Perfect Form

After cutting, the next step in diamond processing is shaping. This is where the diamonds begin to take their final form. Shaping ensures the diamond conforms to the desired shape and dimensions. Whether it’s a round, pear, or princess cut, shaping is where the diamond starts to resemble its final look.

STPL’s LAZER LEAP is the industry’s top diamond shaping machine, allowing for complex and customizable 3D shaping. Powered by precision laser technology, LAZER LEAP is ideal for both round and fancy shapes, and it ensures accuracy at every step. This machine’s flexibility allows it to handle custom shapes, which are increasingly in demand. With features like fast cutting, low maintenance, and zero breakage, LAZER LEAP provides diamond manufacturers with the tools they need to create unique, high-quality diamonds in various shapes and sizes. This precision is vital in ensuring maximum yield and value for each stone.

Shaping a diamond is an intricate process that requires not only skilled operators but also the best technology to ensure perfection in every cut. The increased demand for customized diamond shapes, particularly from the CVD (Chemical Vapor Deposition) segment, has made shaping even more critical, and machines like LAZER LEAP help deliver on this demand.

Diamond Polishing: Achieving the Final Sparkle

The final step in diamond processing is polishing. This is the process of giving the diamond its signature sparkle. Polishing is all about refining the surface of the diamond to enhance its brilliance and light performance. Any imperfections on the surface need to be meticulously removed during this stage to give the diamond a smooth, reflective finish.

STPL’s RoboShine takes polishing to the next level. With its automated robotic technology, it ensures precise polishing with minimal weight loss. RoboShine uses advanced polishing techniques that guarantee the diamond’s brilliance while minimizing the risk of human error. Its robotic technology allows for consistent and flawless polishing, ensuring that each diamond sparkles with the highest level of clarity and brilliance.

Polishing is what gives diamonds their final, breathtaking appearance. RoboShine ensures that each diamond gets the attention it deserves in this crucial final step. With its ability to automate and streamline the polishing process, STPL is at the forefront of innovation in diamond polishing technology.

The Role of Robotic Technology in Diamond Processing

As the diamond industry evolves, automation and robotics play an increasingly crucial role in every stage of diamond processing. STPL has been a pioneer in introducing robotics into diamond shaping and sawing processes. For example, the RoboCut Pro system ensures that up to 50 diamonds can be sawed in one go, with minimal human intervention, drastically improving efficiency and reducing the risk of errors.

Robotic systems are particularly beneficial in tasks like sawing and shaping, where precision is paramount. With the use of advanced robotics, manufacturers can ensure that diamonds are processed with higher speed and accuracy, leading to increased productivity and reduced costs. This is where STPL truly stands out—by offering not only the technology to cut and polish diamonds but also the robotic solutions to do it faster, more accurately, and with better results.
