From Rough to Refined: The Diamond Cutting Process for 2-Carat Gems

Diamond Cutting

A well-cut 3 carat diamond reflects light, dancing with fire, brilliance, and scintillation. The process involves cutting a rough stone and refining it into a faceted gem. A professional cutter sorts the rough, cleaves, shapes, and polishes the facets.

The cutting process of a 3 carat diamond

Analyzing the diamond rough

The manufacturer analyzes the maximum ROI for a piece of rough. This is a complex process that requires state-of-art-technology. First, he determines how much the diamond will sell after polishing.

A scanner gives a three-dimension model of the rough. Next, a skilled cutter decides whether the stone should be cleaved or sawn. After that, he maps the inclusions – the process could take months. For a 3 carat diamond, the cutter can choose pearl, emerald, princess, round, marquise, heart, or oval shapes. From there, the cutting can begin.

Sawing or cleaving the rough

If the plan is to cut out the rough, the stone is divided into pieces. The cutter can use a chisel and a hammer to break it (cleaving). Since a diamond consists of crystals, lasers are used to cut a 3 carat diamond.

Some manufacturers use a specialized saw to cut the rough into different pieces (sawing). But since a diamond is a tough stone, the process can take a couple of hours.

From Rare Carat’s, shoppers can buy fancy-looking 3 carat diamonds that require more skills to cut.

Creating the desired shape

The shape of a 3 carat diamond is created by girding. A computer-controlled machine is used to create a round diamond. The most challenging part is shaping the curves, as seen on Rare Carat

Faceting and polishing

This final step requires the cutter to hold the diamond in the arm (the tang) before placing it in a spinning wheel. At Rare Carat, a 3-diamond carat can feature different shapes like princess, pear, round, etc. Exceptional skills are required to achieve the right symmetry, polish, and proportion. The goal is to give an amazing shine and sparkle.

The cut can also be Poor, Good, Very Good, Fair, or Excellent. The best manufacturers will eliminate the marks to get a smooth reflective surface, as seen on Rare Carat..

The process also requires moving the stone to create a symmetrical design. At its core, facing is done by holding the diamond on a computer to produce the required angle. If there’s an error, that could lean the brilliance instead of reflecting it back to the eye. Fine powder is then used on the sides to create the final beauty.

Interestingly, the polishing process undergoes two more steps to create reflective facets. Some manufacturers prefer blocking to create a template for the next stage. This involves adding crowns, pavilion mains, culet, and table facets. Others use the brillianteer process to finish the job. It’s simply adding more facets to the existing ones.

This last step is both an art and a science – it requires attention to detail. There should be no room for error as it transforms a rough stone to a brilliant jewel. After all, polishing determines the fire, brilliance, and sparkle of the gem.

Factors that determine how a diamond is cut

The manufacturer must consider the following factors before deciding how a diamond should be cut:

  • Original shape of the stone
  • Weight retention
  • Flaws to be eliminated
  • Location of the inclusions

Weight retention

The manufacturer must decide the carat value. For instance, he can choose a 2-carat or 3-carat diamond. If the original crystal is an octahedron, the cutter can create round or square cuts. For oddly shaped crystals, one can make fancy cuts that blend with the original shape. It’s worth mentioning that round cuts command premium pricing.

Color retention

The cut plays a big role in the color of a diamond. Some colors depend on how the stone is naturally made, so manufacturers should decide how they want the final gem to appear. In summary, a brilliant cut involves sawing the rough, setting where the facet is created, bruiting the girdle, and polishing all crown facets.
