Princess Cut Lab Grown Diamonds
Princess cut lab-grown diamonds are highly demanded due to their versatility, durability and high brilliance. They also offer a unique appearance and are cost-effective compared to other diamond cuts, making them a popular choice for engagement rings and other jewelry.
The process of creating a princess cut lab-created diamond begins with selecting a rough diamond and determining the best orientation for cutting. The rough diamond is then cut into a square shape using specialized cutting machines and cut to specific angles to maximize brilliance. The diamond's surface is then faceted and polished to create the traditional princess cut pattern. The finished diamond is then inspected and certified for quality.

How to Choose The Perfect Princess Cut Lab-Grown Diamond?
To achieve a stunning appearance and maximize the play of light in a princess cut lab-grown diamond, it's crucial for the diamond's sides to be uniform, and its facets should be symmetrical. Any excess or missing facets can disrupt the way light reflects within the diamond. In a diamond with an excellent cut, the left and right halves match precisely, and all the facet points align perfectly.
For those seeking an affordable option, selecting a diamond with an SI2 clarity grade can be a wise choice. If the diamond is larger, opting for an SI1-VS2 clarity grade is a better option.
Color imperfections become more noticeable in larger gemstones, just like in round lab diamonds. Choosing a lower color grade like I can be a money-saving choice for lab-created diamonds under 1 carat. However, it's advisable to seek a higher color grade for larger diamonds to avoid any yellowish hues.
Technical Aspects of Princess Cut Diamonds
The princess cut diamond was first invented by Arpad Nagy in 1980. Nagy, a diamond cutter and polisher, was searching for a way to maximize the potential of rough diamonds, and he developed a new cutting technique that resulted in a square or rectangular diamond with a high level of brilliance. The princess cut diamond is also known as the "square modified brilliant" or "barion cut" named after Nagy's friend, Basil Watermeyer, who helped him to develop and promote the cut.
It was a significant breakthrough in diamond cutting, as it allowed diamond cutters to retain more of the rough diamond's weight, resulting in a more cost-effective option for consumers. Nagy's new cutting technique also resulted in a diamond that had a unique and striking appearance, which quickly caught the attention of the diamond industry and consumers alike.
Princess cut lab-grown diamonds became popular due to their unique appearance and high level of sparkle. They are also versatile and can be used in a variety of jewelry settings, from solitaire to three-stone rings, making them ideal for engagement rings and other special occasion jewelry. The princess cut shape is now one of the most popular diamond cuts and it is widely used in the diamond industry.

Princess cut lab grown diamonds are chemically and physically identical to natural diamonds, with the same hardness, brilliance, and fire.
