Princess Cut Engagement Rings: The Complete Buying Guide for 2026

The princess cut is the second most popular engagement ring shape in the world, after the round brilliant. It has been for decades. Despite that longevity, buyers often come to it with questions that are genuinely hard to find good answers to: what exactly makes a princess cut different from other square cuts, how do you evaluate cut quality, what settings work best, and what does a good princess cut ring actually cost in Canada?

This guide answers all of it.

What Is a Princess Cut?

A princess cut is a square (or slightly rectangular) shaped gemstone with pointed corners and a modified brilliant faceting pattern. Where a round brilliant has 57–58 facets, a princess cut typically has 76 facets arranged in a pattern specifically designed to maximize brilliance in a square shape. The result is a stone with exceptional sparkle — among the highest of any square cut — and a clean, geometric silhouette that reads as contemporary and structured.

The princess cut was developed in the 1980s and became commercially prominent through the 1990s and 2000s. Its continued popularity comes down to a straightforward combination: the round brilliant’s level of brilliance, in a square shape that’s perceived as more distinctive and modern than the classic circle.

Princess vs. Other Square Cuts: The Key Differences

Buyers often conflate several square or near-square cuts. Here’s how the princess compares to the most common alternatives:

Princess vs. Cushion cut: Both are square (or near-square), but the princess has sharp pointed corners while the cushion has rounded corners. The princess reads as harder-edged and more geometric; the cushion reads as softer and more romantic. The cushion’s facet pattern produces a different sparkle character — broader, chunkier flashes vs. the princess’s sharper, more brilliant scintillation.

Princess vs. Asscher cut: The Asscher is an octagonal step cut — it has cropped corners and long, linear facets (like an emerald cut, but square). The Asscher produces a “hall of mirrors” effect rather than brilliant sparkle. Very different aesthetics: princess is brilliant and sparkly; Asscher is architectural and vintage.

Princess vs. Radiant cut: Both are brilliant-cut square stones, but the radiant has cropped corners (like an emerald cut’s silhouette with brilliant facets). The princess has pointed corners; the radiant has cut corners. The radiant is slightly more forgiving of inclusions due to its different facet pattern.

The Corner Problem: Why Setting Choice Is Critical for Princess Cuts

The princess cut’s four pointed corners are its most distinctive feature — and its primary vulnerability. Sharp corners are chip points. If a corner is struck against a hard surface at the wrong angle, it can chip. This is not a common occurrence with careful wear, but it’s a real consideration.

The practical solution: a four-prong setting where each prong covers one corner. This is the standard and correct setting for a princess cut — it protects the four corners while allowing the stone’s flat top table to remain fully visible. Some buyers choose a bezel setting for maximum corner protection, though this partially conceals the stone’s edges.

A six-prong setting, which works well for round brilliants, is not typically used for princess cuts because the corners need the direct coverage that four corner-prongs provide.

Length-to-Width Ratio: Getting the Shape Right

A princess cut’s shape is described by its length-to-width (L:W) ratio. A ratio of 1.0:1 is a perfect square. Most buyers prefer princess cuts in the 1.0:1 to 1.05:1 range — anything above 1.10:1 starts to look noticeably rectangular rather than square.

If the square appearance is important to you, verify the L:W ratio before purchasing. This is particularly relevant for moissanite princess cuts, where the specification can be confirmed with the jeweler. A ratio of 1.0 to 1.03 is where most buyers land for a clean square appearance.

Evaluating Cut Quality in a Princess Cut

Cut quality affects how much light the stone returns. A well-cut princess appears bright and even across the entire table; a poorly cut princess has dark areas (windowing) or uneven brilliance. Key indicators of good cut quality:

• Even brightness across the table. Looking down at the stone from above, the brilliance should be consistent across the whole face, not concentrated in the centre with dark edges.
• Sharp corners with no rounding. The four corners of a well-cut princess should be crisp and pointed, not slightly rounded from cutting shortcuts.
• Symmetry. The stone should be visually square (if intended as square) with facets that mirror each other evenly across both axes.

For moissanite princess cuts at Toronto Fine Jewelry, stone quality is standardized at DEF colour and VVS1 clarity — the top grade for colour and near-flawless clarity. You’re not evaluating these variables stone by stone; the specification is consistent.

Settings That Work Best With Princess Cuts

Solitaire (four-prong corner setting). The classic princess cut presentation. Clean, minimal, lets the stone’s geometric character speak for itself. The most timeless option and the easiest to pair with a wedding band.

Square halo. A halo of small stones in a square configuration surrounding the princess centre. This amplifies the perceived size significantly and adds substantial brilliance. The square halo-on-princess combination is one of the most photographed ring styles and particularly popular among buyers who want maximum visual impact.

Channel-set side stones. A three-stone design with channel-set baguette or princess-cut side stones creates a contemporary, structured look. The geometric consistency of square-on-square settings is a strong aesthetic choice for buyers who like clean, architectural jewelry.

Is the Princess Cut Right for Your Partner?

• Want maximum brilliance in a non-round shape
