The Process of Cutting and Polishing Fancy Color Diamonds

Fancy color diamonds are a marvel of nature, renowned for their vibrant hues and stunning brilliance. Unlike their colorless counterparts, these diamonds consist of 1% of the diamond world and require specialized techniques in both cutting and polishing to enhance their unique characteristics. At Paloma, we take pride in our meticulous process that transforms rough stones into exquisite gems, ready to dazzle and delight.

Evaluation of the Rough Diamond

The journey of a fancy color diamond begins with a thorough evaluation of the rough stone. Expert gemologists assess the diamond's natural color, inclusions, and overall shape. This evaluation is crucial as it determines the potential value and the optimal cutting strategy to maximize both color and carat weight.

Planning the Cut

Once the rough diamond is evaluated, the planning stage involves advanced technology and skilled craftsmanship. Using state-of-the-art 3D modeling software, our artisans map out the best way to cut the diamond. This stage is particularly critical for fancy color diamonds as the cut can significantly affect the intensity and distribution of color. The goal is to minimize waste while enhancing the diamond's natural beauty. 

At Paloma, we dedicate our diamond specialists to do a thorough inspection of all the possibilities when presented with rough color diamonds and find potential in unique shapes and cuts. 

Cutting the Fancy Color Diamonds

Cutting fancy color diamonds requires precision and patience. At Paloma Diamond, we employ master cutters who have honed their skills over decades. The rough diamond is carefully sawed and shaped using lasers and other specialized tools. Each cut is meticulously executed to bring out the stone's best features. For fancy color diamonds, maintaining and enhancing color is a priority, often involving intricate cuts that are different from those used for colorless diamonds.

Some diamond cuts can highlight the brilliance of the diamond and some display the color in a different manner with a step cut. There are other types of cuts that might highlight the qualities of a fancy color diamond's intensity. So experts asses this when planning the cutting and assure the enhancing of the best qualities of each color diamond in the best way they can.

Polishing Fancy Color Diamonds

Polishing is where the diamond achieves its final brilliance. The diamond is carefully polished to smooth out any rough edges and to enhance its luster. Polishing wheels coated with diamond dust are used to achieve a mirror-like finish. This step is essential for showcasing the stone's color and clarity, ensuring that every facet sparkles with maximum light return.

Quality Control and Qualifications of GIA

Before a fancy color diamond is deemed ready, it undergoes rigorous quality control checks. Each diamond is inspected for any imperfections that may have occurred during the cutting and polishing process. This ensures that only the finest stones make it to the market.

The involvement of GIA certification or any other gemologist organization is required to asses the outmost value of the stone at hand. 


The process of cutting and polishing fancy color diamonds is an intricate art form that combines advanced technology with expert craftsmanship. At Paloma, our commitment to excellence ensures that each diamond we produce is a masterpiece, ready to bring joy and beauty to its wearer.
