Emerald Cut Diamond Rings

How Is Diamond Rough Transformed Into An Emerald Cut Bezel Ring?

An emerald cut bezel ring will make you stand out from the crowd with an impressive statement piece on your finger. Emerald cut diamonds are said to evoke elegance and modern styles, even though the diamond cut dates back to the 15th Century. Regardless, emerald cut engagement rings are becoming more and more popular because women prefer unique and distinctive jewelry pieces these days.

The emerald cut was introduced in the diamond cutting industry when a stonecutter saw that the step-cut gave the gemstones more stability. An emerald cut diamond will feature a rectangular shape with analogous receding lines. There will be several rows of stepped facets on the stone’s crown and pavilion, running parallel to the girdle. The diamond will have 58 facets (57 in some cases) and will exhibit a “hall of mirrors” effect. Yet because of the concentric alignment of the facets, the fire and brilliance of emerald cut diamonds will be a little lesser than that seen with round brilliant cut diamonds.

Only around 3% of the diamonds available in the market today feature emerald cut. This means that they are very rare to find and will surely be a stylish accessory to flaunt forever. The larger surface area in emerald cut diamonds also makes them appear to be bigger than a round cut diamond having the same carat weight. This allows you to have a huge rock to show off on your big day, but for a reasonably lower price. Below is how diamond rough is cut and polished to transform it into a stunning sparkler for your emerald cut bezel ring.

How Are Diamonds Cut And Polished From Roughs

Diamond rough is formed in the Earth’s mantle and is brought to the surface by deep-source volcanic eruptions through kimberlite pipes. After the rough diamonds are mined from the explosive deposits, they are sent for the diamond cutting process. The first thing that a diamond cutter takes into account is how to shape the stone into a masterpiece. The stonecutter analyzes the proportioning of facets and plans the symmetry and polish that can be achieved with computer simulations.

Planning the cut of the rough diamond can be a time-consuming process. That is because experts follow all the procedures and standards carefully to determine how the final product can be attained with minimal wastage. As they aim to maximize the yield of the rough diamond, this also decides the final value of the finished sparkler. Generally, a Sarin machine is used to assess the accurate measurements for cutting the rough diamond. This will help to generate 3D models on a computer showing the best possible ways to cut the stone.

The next step is cleaving or sawing the rough diamond. This process involves splitting the extracted diamond rough into separate pieces as per the measurements formulated earlier. After segmenting the diamond rough into smaller parts, the stonecutter can work on them individually to utilize the rough properly. The diamond cutter may also use mechanical sawing or laser sawing during this stage to get the desired results. This is especially applicable for oddly shaped diamond roughs.

Then comes the bruting phase, in which the stonecutter works on the rough diamond to form the outline of the finished product. This stage is also known as girdling, as this is when the girdle of the diamond is shaped. The bruting process involves using another diamond placed on a rotating wheel to grind the diamond rough into the desired shape. This is because diamond is the hardest mineral on Earth and it will take another diamond to actually cut through the material.

After the girdle is finished, the rough diamond is sent for polishing. This process gives the diamond its facets, which determine its reflective properties. It involves placing the girdled rough diamond on a rotating arm and using a spinning wheel to polish it. The polishing stage can be further divided into two parts: blocking and brillianteering. In the first one, the stone is given 8 crowns, 8 pavilion mains, 1 table facet, and 1 culet as per the initial plan. Then the brillianteer will finish the polishing by adding the remaining facets to get to the desired diamond shape. This will determine the fire and brilliance of the finished diamond.

When that is done, the polished diamond is sent for inspection. The diamond is checked meticulously by experts to make sure that all the specifications set in the planning phase are met by the diamond cutters. If anything seems missing, the diamond is sent back to the stonecutter for final touch-ups. This is to ensure that the diamond meets all the quality control standards. If needed, it will be sent for re-cutting too. While that can hurt the carat weight of the diamond, re-cutting can improve the clarity grade of the diamond and result in a more brilliant sparkler.
