When it comes to choosing a diamond cut, the square diamond cut, also known as a princess cut, is a popular and captivating choice. This cut is renowned for its unique beauty and sparkle, making it a favorite among diamond enthusiasts. In this article, we'll delve into the world of square diamond cuts, exploring their characteristics, history, and why they remain a timeless choice.

Understanding the Square Diamond Cut

The square diamond cut is a variation of the round brilliant cut, with a square outline instead of a round one. It was first introduced in the 1960s and gained popularity due to its modern, geometric shape and exceptional sparkle. The cut is characterized by its four equal sides and pointed corners, with a depth ratio typically ranging from 73% to 78%.
Princess Cut vs. Square Emerald Cut

It's essential to distinguish between the princess cut and the square emerald cut. While both have a square outline, they differ in their internal patterns and facet arrangements. The princess cut has a step-cut pavilion with large, mirrored facets, while the square emerald cut has a step-cut pavilion with long, narrow facets.
- Princess Cut: Step-cut pavilion with large, mirrored facets
- Square Emerald Cut: Step-cut pavilion with long, narrow facets

The Allure of the Square Diamond Cut
The square diamond cut's appeal lies in its combination of modern aesthetics and traditional craftsmanship. Its square outline makes it an excellent choice for those who prefer a more geometric, contemporary look. Moreover, the cut's step-cut pavilion allows for excellent light reflection, resulting in a captivating sparkle that rivals that of round brilliant cuts.
Setting Options for Square Diamond Cuts

Square diamond cuts can be set in various ways to enhance their beauty. Some popular setting options include:
- Prong setting: Four prongs hold the diamond in place, allowing maximum light reflection and showcasing the diamond's shape
- Bezel setting: A thin metal rim encases the diamond's edge, providing added security and a sleek, modern look
- Channel setting: The diamond is set between two parallel rows of small stones, creating a continuous, seamless line of sparkle
Famous Square Diamond Cuts in History

Throughout history, square diamond cuts have adorned the fingers of royalty and celebrities alike. One notable example is the Tiffany Diamond, a 128.54-carat fancy yellow diamond cut in a cushion-square modified brilliant cut. This iconic diamond, discovered in 1877, is one of the largest and most famous square diamond cuts in the world.
Caring for Your Square Diamond Cut
















To maintain the brilliance and beauty of your square diamond cut, regular cleaning is essential. Use a mild dish soap and warm water to clean your diamond, then gently brush it with a soft-bristled brush. Avoid using harsh chemicals or abrasive materials, as they can damage the diamond's facets. Additionally, store your diamond separately from other jewelry pieces to prevent scratches.
In conclusion, the square diamond cut is a captivating and timeless choice for those seeking a modern, geometric look with exceptional sparkle. Whether you're drawn to its contemporary aesthetics or its rich history, a square diamond cut is sure to make a statement. By understanding the unique characteristics and care requirements of this captivating cut, you can ensure that your square diamond cut remains a sparkling and cherished treasure for generations to come.
