The princess cut diamond remains one of the most chosen diamond styles for engagement rings and fine jewelry. Its clean shape, bright sparkle, and modern look appeal to buyers who want a strong visual presence without traditional round styling. This guide explains how princess cut diamonds perform, how they look when worn, and how to select one with confidence.
Many people choose this cut for its sharp lines and bold light return. Others appreciate how the square shape balances cost and visual presence. While trends change over time, this popular diamond style continues to hold steady interest because it suits many ring designs and hand shapes.
This princess cut diamond guide covers fire, style, proportions, clarity choices, and setting options. It also explains what to watch for before buying and how this cut compares to others.

What Is a Princess Cut?
A princess cut diamond has a square or slightly rectangular outline with pointed corners. The cut uses a brilliant-style faceting pattern that reflects light in many directions. This structure gives the stone bright flashes and strong contrast.
Most princess cut diamonds feature:
- Four sharp corners
- A square or near-square face
- A deep pavilion with chevron facets
The cut became popular in the late 20th century and quickly rose in demand. Buyers liked its sharp geometry and lively sparkle. Since then, jewelers have refined cutting methods to improve balance and light return.
A square princess cut usually has a length-to-width ratio between 1.00 and 1.05. Stones above this range appear more rectangular.
What You Need to Know About the 4 Cs for Princess Cut Diamonds
The 4 Cs apply to all diamonds, but they carry different weight. When evaluating princess cuts specifically, priorities shift.
Cut Quality Matters Most

Cut remains the most critical factor for princess cuts.
Grading labs don’t rate fancy cut quality. This means you need to personally assess the stone’s proportions. Look for specific measurements:
- Depth percentage: 68-72%
- Table size: 68-73%
- High symmetry ratings
- Even corner measurements
- Properly aligned facets
- Consistent light performance
Ask your jeweler for these measurements before purchasing. The symmetry should be high. All corners should measure evenly.
Facets should align properly throughout the diamond. These specifications determine the stone’s sparkle and fire. They’re worth investigating thoroughly.
Clarity Grade Selection
Clarity should target SI1 or higher for princess cuts.
The facet pattern means visible inclusions appear more readily. You need to account for this when shopping. Here’s what to know:
- SI1 clarity is the minimum target
- Eye-clean diamonds recommended
- Higher clarities offer more insurance
- Inclusions more visible than round cuts
- Budget considerations important
- VS2 offers good balance for many buyers
SI1 provides a good starting point for princess cuts. However, VS2 clarity offers additional peace of mind. The price difference often justifies the upgrade.
Eye-clean diamonds should be your baseline. This means no visible inclusions to the naked eye. Professional grading becomes helpful here.

Color Grade Recommendations
Color carries more importance with princess cuts than round diamonds.
The large table facet reflects body color throughout the stone. This affects how the diamond appears. Consider these guidelines:
- H color or higher recommended for white metals
- G color excellent for budget-conscious buyers
- F color provides maximum colorlessness
- I color may show slight tints in white settings
- Yellow or rose gold hides color better
- Budget and metal choice influence decisions
For white gold or platinum settings, aim for H color or higher. The white metal provides contrast that makes color more apparent. This affects the overall visual impact.
Yellow gold or rose gold settings hide color better. You might get away with an I or J color in warmer metals. Your setting choice influences your color grade needs.
Carat Weight Considerations
Carat weight feels less important than other factors for princess cuts.
The square shape means excellent size visibility. Two carats of princess cut looks substantial on the hand. Consider these points:
- 1 carat appears larger than 1 carat round
- 1.5 carats provides excellent size for most buyers
- 2 carats offers impressive presence
- Budget often determines final choice
- Visual impact matters more than carat weight
- Prioritize cut quality over raw carat weight
Prioritize cut quality over raw carat weight. A well-cut 1.5 carat stone outshines a poorly cut 2 carat diamond. The sparkle difference becomes immediately apparent.
Lab-Grown vs Natural vs Moissanite Princess Cut Stones
Choosing a princess cut stone often comes down to three options: natural diamonds, lab-grown diamonds, and moissanite.
All three can look beautiful in a square princess cut, but they differ in origin, price, sparkle, and value.
| Feature | Natural Diamond | Lab-Grown Diamond | Moissanite |
|---|---|---|---|
| Origin | Formed naturally within the earth over billions of years | Created in advanced laboratory conditions | Lab-created gemstone |
| Composition | Pure carbon crystal | Pure carbon crystal (same as natural diamond) | Silicon carbide (not a diamond) |
| Appearance | Natural, classic brilliance | Visually identical to natural diamond | Extra bright with rainbow-like appearance |
| Sparkle Type | Balanced white brilliance | White diamond-like sparkle | High fire with rainbow sparkle |
| Hardness | 10 Mohs scale | 10 Mohs scale | 9.25 Mohs scale |
| Durability | Lifetime durability | Very strong for daily wear | Durable, slightly less than diamond |
| Price Level | Highest price | More affordable than natural diamond | Most affordable option |
| Ethical / Sourcing | Mining required (depends on source) | Conflict-free, lab controlled production | Ethical, lab-created |
| Certification | GIA, AGS available | IGI, GIA available | Limited certification availability |
| Best For | Luxury, tradition, long-term value | Real diamond look with budget flexibility | Maximum sparkle at lower cost |
Best Settings for Princess Cut Diamonds
Setting choice matters more for this cut than for rounded shapes. The pointed corners need support to reduce wear over time.
Solitaire Settings
A solitaire setting places full focus on the diamond. For princess cuts, prongs should cover each corner securely.
Common solitaire styles include:
- Four-prong corner settings
- V-prong designs for extra corner protection
This setting suits buyers who want a clean and timeless look.
Halo Settings
Halo settings surround the center stone with smaller diamonds. This style adds size and sparkle while protecting the corners.
Benefits of halo settings:
- Increased visual size
- Extra light reflection
- Improved corner coverage
Princess cut halo rings remain popular for engagement rings because they combine structure with added brilliance.
Bezel Settings
A bezel setting wraps metal around the edges of the diamond. This style offers the most protection for corners.
Advantages include:
- Strong security
- Smooth outer edges
- Modern appearance
Bezel settings make square-shaped diamonds ideal for active lifestyles and daily wear.
Channel and Side-Stone Settings
Channel settings place accent stones within the band. Side stones add width and detail.
These designs:
- Add visual weight to the ring

- Pair well with straight wedding bands
Square center stones pair beautifully with channel-set bands.
