When it comes to choosing a princess cut diamond, one of the critical decisions revolves around size. Understanding the relationship between millimeters (mm) and carat weight can help you make an informed decision. This guide aims to provide you with expert insights on interpreting a princess cut diamond size chart, so you can select the perfect gemstone for your jewelry.
The Princess Cut – A Brief Overview:
The princess cut is a modern diamond shape characterized by its sharp, uncut corners and an array of intricate facets, typically either 58 or 76, which give it a unique brilliance and fire. It’s a preferred choice for those seeking a contemporary look with the sparkle that can rival the classic round brilliant cut.
Princess Cut Diamond Size Chart Explained:
A diamond’s size is initially measured in millimeters, which refers to the length and width of the stone as viewed from the top. For princess cut diamonds, since the shape is square, the length and width are typically the same. However, the carat weight doesn’t directly correspond to the mm size because it also depends on the depth and density of the diamond.
Below, we provide a general chart that correlates mm measurements to carat weight for princess cut diamonds. Please note that these are approximations, and actual weights may vary based on the specific dimensions and cut quality of the stone.
| Length x Width (mm) | Approximate Carat Weight |
|---|---|
| 1.5 x 1.5 | 0.015 ct |
| 2.0 x 2.0 | 0.05 ct |
| 2.5 x 2.5 | 0.10 ct |
| 3.0 x 3.0 | 0.20 ct |
| 3.5 x 3.5 | 0.30 ct |
| 4.0 x 4.0 | 0.50 ct |
| 4.5 x 4.5 | 0.70 ct |
| 5.0 x 5.0 | 0.90 ct |
| 5.5 x 5.5 | 1.10 ct |
| 6.0 x 6.0 | 1.40 ct |
| 6.5 x 6.5 | 1.70 ct |
| 7.0 x 7.0 | 2.00 ct |
| 7.5 x 7.5 | 2.50 ct |
| 8.0 x 8.0 | 3.00 ct |
| 8.5 x 8.5 | 3.50 ct |
| 9.0 x 9.0 | 4.10 ct |
| 9.5 x 9.5 | 4.60 ct |
| 10.0 x 10.0 | 5.20 ct |
Understanding Carat Weight:
The carat weight of a diamond is a measurement of its weight, not necessarily its size. Two diamonds with the same mm measurements can have different carat weights if one is cut deeper than the other. Hence, a deeper cut diamond with more significant mm dimensions might have the same carat weight as a shallower diamond with smaller mm dimensions.
Expert Tips on Selecting the Right Size:
- Consider Proportions: The beauty of a princess cut diamond lies in its perfect square shape. Look for a length-to-width ratio close to 1.00-1.05 for a square princess cut.
- Prioritize Cut Quality: A well-cut princess diamond will appear larger and more brilliant, as it reflects light more efficiently. A poor cut can make the diamond look smaller and duller, despite its carat weight.
- Balance Carat and Clarity: Larger carat weights can highlight imperfections. If you opt for a bigger stone, ensure the clarity is high enough that inclusions are not visible to the naked eye.
- Set a Budget: Carat weight significantly affects the price. Choose the best carat size that fits within your budget, without compromising on cut, color, and clarity.
Conclusion:
While the princess cut diamond size chart is a valuable starting point, your choice should also consider personal preference, style, and budget. Consult with a trusted jeweler and view diamonds in person when possible. This ensures that you find a princess cut diamond that not only fits the measurements you seek but also has the sparkle and aesthetic you desire. Remember, the right diamond is the one that speaks to you, regardless of its size on a chart.
