A princess cut diamond combines modern geometry with exceptional sparkle, making it one of the most popular shapes for engagement rings and fine jewelry. Here is everything you need to know, from shape and size to the settings that show princess cut diamonds off best.
What Is a Princess Cut Diamond?
The princess cut is a square or rectangular brilliant-cut diamond with pointed corners and a flat top. Designed to bring the fire of a round cut into a geometric silhouette, the princess shape diamond feels both modern and timeless.
The Origin and Princess Cut Diamond Meaning
The princess cut diamond meaning is rooted in contemporary craftsmanship. Created in 1979 by Israel Itzkowitz, the cut maximizes brilliance in a square form while preserving more of the rough diamond during cutting. The name quickly gave the shape its aspirational appeal, and the cut rose to prominence in the 1980s. Today, the princess cut remains a favorite for women who love bold, modern design with lasting value.
What Does a Princess Cut Diamond Look Like
So, what does a princess cut diamond look like up close? Picture a square face with four sharp corners and a flat table on top. Underneath, the diamond tapers into an inverted pyramid. Most princess cuts feature around 57 facets in a modified brilliant pattern that creates dazzling flashes of light. From above, the stone appears clean and angular, while the deep pavilion gives it an architectural quality from the side.
How to Choose a Princess Cut Diamond?
Selecting the right princess cut comes down to the four Cs: cut, color, clarity, and carat weight. Each factor influences how your diamond looks on the finger and how it fits within your budget.
Cut, Color, and Clarity Guidelines
- Cut is the most important factor. A well-cut princess diamond reflects light evenly and creates a balanced pattern of bright and dark areas. Avoid stones with a steep pavilion, which can make the diamond appear dark.
- Color grades between F and H work beautifully. The brilliant faceting pattern helps conceal subtle warmth, so you do not need to reach the very top of the scale.
- Clarity is forgiving in princess cuts. VS1 or even SI1 grades often appear eye-clean because the complex facet arrangement naturally hides minor inclusions.
Carat Weight and the Princess Diamond Size Chart
Because much of a princess diamond's weight sits in its deep pavilion, the stone can face up slightly smaller than other shapes at the same carat weight. A princess diamond size chart offers approximate face-up dimensions:
| Carat Weight | Approximate Face-Up Size (mm) |
|---|---|
| 0.50 ct | 4.0 x 4.0 |
| 0.75 ct | 4.8 x 4.8 |
| 1.00 ct | 5.5 x 5.5 |
| 1.50 ct | 6.2 x 6.2 |
| 2.00 ct | 6.9 x 6.9 |
Individual proportions vary, so always view the diamond before purchasing.
Best Settings for Princess Cut Diamonds
The right setting protects those four-pointed corners from chipping and frames the stone's geometry. When browsing fine diamond rings, consider which style matches your lifestyle.
Solitaire and Four-Prong Settings
A four-prong solitaire is the classic choice. Each prong sits at a corner, shielding the vulnerable points while letting maximum light enter the stone. The result is a clean, timeless look that puts all focus on the diamond.
Bezel, Halo, and Cathedral Styles
- Bezel settings wrap a thin rim of metal around the entire diamond, offering excellent corner protection and a sleek, modern look.
- Halo settings surround the princess cut with smaller diamonds, adding visual size and extra sparkle.
- Cathedral settings feature arched bands that rise to meet the center stone, creating a refined, graceful silhouette.
| Setting Style | Corner Protection | Visual Impact | Best For |
|---|---|---|---|
| Four-Prong Solitaire | Good | True to size | Classic, minimalist taste |
| Bezel | Excellent | Slightly larger | Active lifestyles |
| Halo | Good | Appears larger | Maximum sparkle |
| Cathedral | Moderate | True to size | Elegant, vintage-inspired looks |
Any of these pair wonderfully with a diamond wedding band for a cohesive bridal set.

Frequently Asked Questions
Q. Do princess-cut diamonds chip easily?
The four pointed corners are more susceptible to damage than rounded shapes. A prong or bezel setting protects corners effectively, making the right setting essential for long-term wear.
Q. Are princess-cut diamonds less expensive than round brilliants?
Yes. Princess cuts typically cost less per carat than round brilliants of comparable quality because more of the rough diamond is preserved during cutting.
Q. What is the ideal length-to-width ratio for a square princess cut?
For a true square appearance, look for a length-to-width ratio no greater than 1.05:1. Anything above that will appear slightly rectangular, which is a valid preference but a different aesthetic.
Q. Can a princess-cut diamond be rectangular?
Yes. While most princess cuts are square, the shape can also be slightly rectangular. A length-to-width ratio above 1.10:1 will give a noticeably elongated appearance.
Q. What is the best depth percentage for a princess cut diamond?
A depth between 64% and 75% is generally considered ideal, with most well-cut princess diamonds falling around 70%.
Q. Do princess-cut diamonds look smaller than round diamonds of the same carat weight?
Due to their deeper pavilion, princess cuts can appear slightly smaller face-up than a round brilliant of the same carat weight. Going up slightly in carat can offset the difference if size is a priority.
