Princess Cut Diamonds: A Modern Marvel of Brilliance

The Princess cut is a contemporary classic in the world of diamond shapes. Known for its square outline and exceptional brilliance, it offers a stunning alternative to the traditional round brilliant. This cut masterfully balances fire and sparkle, making it a popular choice for engagement rings and other fine jewelry.

Definition

The Princess cut, also known as a modified brilliant-cut square or square modified brilliant, is a diamond shape characterized by its square or rectangular outline and a brilliant-cut facet pattern. Unlike the round brilliant cut, which is optimized for maximum sparkle with 57 or 58 facets, the Princess cut typically features 58 or 76 facets, depending on whether the crown and pavilion facets are counted. Its design aims to maximize the brilliance and fire of a diamond while minimizing waste during the cutting process, often being cut from the corners of a rough diamond that might otherwise be unsuitable for a round cut.

Key Features

• Square or Rectangular Outline: The most defining characteristic is its shape. It can range from perfectly square to slightly rectangular.
• Brilliant-Cut Facets: The crown (top) of the diamond is typically faceted like a traditional brilliant cut, while the pavilion (bottom) is often composed of chevron-shaped facets, contributing to its exceptional sparkle.
• High Brilliance and Fire: The intricate facet arrangement of the Princess cut effectively reflects light, resulting in dazzling brilliance and vibrant fire.
• Potential for Inclusions: Due to the nature of cutting from rough diamonds, inclusions can sometimes be concentrated near the girdle or corners, which can be a consideration for durability.
• Modern Aesthetic: It offers a contemporary and elegant look, appealing to those seeking a modern design.

Origin and History

The modern Princess cut has roots in earlier square-shaped cuts. The 'Quadrillion' cut, developed in the 1970s, is considered a direct precursor. However, the Princess cut as we know it today was refined and popularized in the 1980s by Israeli diamond cutters. Its development was driven by a desire to create a square shape that retained the brilliance of the round cut and to efficiently utilize rough diamonds, thereby reducing costs. Its rapid rise in popularity is a testament to its striking beauty and value proposition.

Types / Variations

While the standard Princess cut is the most common, variations exist primarily based on the facet arrangements in the pavilion and the precise aspect ratio of the outline:

• Standard Princess Cut: Features a facet pattern similar to a round brilliant on the crown and a pavilion with chevron facets.
• Hari Princess Cut: A more complex version with additional facets for enhanced sparkle.
• Triple Excellent Princess Cut: Refers to a Princess cut diamond that has achieved the highest grades for cut, polish, and symmetry from a reputable grading laboratory.
• Aspect Ratio: Princess cuts can be perfectly square (1:1 ratio) or rectangular (e.g., 1.15:1, 1.20:1). The ideal ratio is subjective and depends on personal preference and the intended setting.

How It's Made

The creation of a Princess cut diamond involves meticulous craftsmanship. It typically starts with a rough diamond, often one with significant inclusions or internal flaws that make it unsuitable for a round cut. The cutter aims to maximize the yield from the rough stone, meaning less diamond material is wasted. The process involves:

1. Girdle and Outline: The rough diamond is sawn or laser-cut to create a square or rectangular outline with sharp corners.
2. Crown Faceting: The top part of the diamond (the crown) is faceted similarly to a round brilliant cut, aiming for optimal light reflection.
3. Pavilion Faceting: The lower part (the pavilion) is faceted with V-shaped or chevron facets that meet at the culet (the bottom point). The precise angle and number of these facets are crucial for the diamond's sparkle.
4. Polishing: All facets are polished to a high degree of smoothness to enhance brilliance.

The skill of the cutter is paramount in achieving a well-proportioned Princess cut that maximizes its optical properties.

Grading & Quality Standards

Like all diamonds, Princess cut diamonds are graded based on the 4Cs: Carat, Cut, Color, and Clarity. However, for the Princess cut, specific considerations apply:

• Cut: While laboratories like GIA do not assign a specific cut grade to fancy shapes like the Princess cut, visual appeal and overall proportions are key. Look for a well-defined facet pattern, good symmetry, and depth that allows for maximum brilliance without appearing too dark or glassy. Ideal depth percentages typically range from 65-75%, and table percentages from 65-70%.
• Color: Colorless to near-colorless grades (D-J) are generally preferred. For Princess cuts, slight yellow or brown tints can be more noticeable than in round diamonds, especially in larger stones, so F-K is often recommended.
• Clarity: Due to the brilliant-cut faceting, which tends to hide imperfections well, inclusions are often less visible than in step cuts. However, inclusions near the sharp corners can be prone to chipping. Aim for a clarity grade of VS1-SI1 for a good balance of clarity and value, ensuring inclusions are not eye-visible.
• Symmetry: Crucial for sparkle. Look for evenly cut facets and sharp, well-defined points.

Buying Guide

When purchasing a Princess cut diamond, consider the following:

• Shape and Proportions: Decide if you prefer a perfectly square shape or a slightly elongated one. Check that the diamond is well-proportioned, with sharp, crisp facet lines and an even distribution of light and sparkle.
• Setting Style: Princess cuts look stunning in various settings. Four-prong or six-prong solitaire settings are popular, as are halo settings that enhance their sparkle and perceived size. Be mindful of the corners, which can be more vulnerable to chipping. Consider a setting that offers some protection, such as a bezel setting or V-prongs.
• Budget: Princess cuts are typically more affordable per carat than round brilliant diamonds because they can be cut from rough diamonds with less waste. This makes them an excellent option for those seeking a larger diamond for their budget.
• Certification: Always purchase a diamond with a grading report from a reputable gemological laboratory (e.g., GIA, AGS).
• In-Person Inspection: If possible, view the diamond in person under good lighting to assess its sparkle and check for any visible inclusions or imperfections.

Price Range & Value Factors

Princess cut diamonds generally offer better value for money compared to round brilliant diamonds of equivalent quality. This is primarily due to the higher yield from the rough diamond when cutting a square shape.

• Price per Carat: You can often expect to pay 10-30% less per carat for a Princess cut compared to a round brilliant of similar quality.
• Value Factors: The 4Cs (Cut, Color, Clarity, Carat) significantly influence the price. However, for Princess cuts, proportions and the visual appeal of the sparkle can sometimes outweigh minor deviations in color or clarity, especially if those imperfections are not eye-visible. The precision of the facet arrangement and the overall brilliance are key value drivers.

Care and Maintenance

Caring for a Princess cut diamond is similar to caring for other diamond jewelry:

• Regular Cleaning: Clean your diamond regularly with a soft brush, warm water, and mild dish soap. Rinse thoroughly and dry with a lint-free cloth.
• Avoid Harsh Chemicals: Remove jewelry before swimming, cleaning with household chemicals, or applying lotions and perfumes, as these can dull the diamond's sparkle over time.
• Professional Inspection: Have your jewelry professionally inspected and cleaned by a jeweler at least once a year to ensure the setting is secure and the diamond is free from damage.
• Storage: Store your Princess cut diamond jewelry separately to prevent scratching other items or being scratched.

Pros and Cons

Pros:

• Brilliance and Sparkle: Offers exceptional fire and brilliance comparable to a round cut.
• Value: Generally more affordable per carat than round brilliant diamonds.
• Modern Aesthetic: Provides a contemporary and stylish look.
• Versatility: Suits a wide range of jewelry styles and settings.
• Excellent for Engagement Rings: A very popular choice due to its beauty and relative affordability.

Cons:

• Vulnerable Corners: The sharp corners are susceptible to chipping or abrasion if not protected by the setting.
• Inclusions: Rough diamond wastage means inclusions can sometimes be concentrated, requiring careful selection.
• Not Ideal for All Settings: Settings must be chosen carefully to protect the corners.
• Slightly Less Fire than Round: While brilliant, some argue the fire might be slightly less intense than a perfectly cut round brilliant due to its shape and facet structure.

Famous Examples

While perhaps not as frequently highlighted in history as some iconic round diamonds, many stunning Princess cut stones exist. The beauty of the Princess cut often lies in its modern appeal and accessibility rather than singular famous historical pieces. Many significant, high-carat Princess cut diamonds have been featured in private collections and high-profile jewelry designs, showcasing their contemporary elegance and brilliance.

Common Misconceptions

• Princess cuts are always square: While many are square, they can also be rectangular. The term 'Princess cut' itself usually implies a square or near-square shape.
• Princess cuts are less brilliant than round cuts: While the facet arrangement differs, a well-cut Princess cut offers exceptional brilliance and fire, rivaling that of a round brilliant.
• They are always cheaper: While generally more affordable per carat than round brilliants, exceptionally large, high-quality Princess cuts can still command very high prices.

FAQs

Is a Princess cut diamond good for an engagement ring?

Yes, the Princess cut is an extremely popular choice for engagement rings. It offers exceptional sparkle, a modern aesthetic, and is often more affordable per carat than a round brilliant, allowing for a larger stone within a given budget. However, it is important to choose a setting that protects its delicate corners.

Are Princess cut diamonds more expensive than round diamonds?

Generally, Princess cut diamonds are less expensive per carat than round brilliant diamonds of comparable quality. This is mainly because the cutting process for a Princess cut is more efficient, resulting in less waste from the rough diamond.

Which is better, Princess cut or Round brilliant?

The 'better' cut depends entirely on personal preference. Round brilliants are the standard for maximum brilliance and have a classic appeal. Princess cuts offer a modern, square look with comparable sparkle and often better value. Consider which shape and style you prefer and how it fits your budget and lifestyle.

How do I protect the corners of a Princess cut diamond?

The corners of a Princess cut diamond are its most vulnerable points. To protect them, opt for settings like a bezel setting (which fully encases the diamond's edge) or a prong setting that incorporates V-shaped prongs at the corners. A halo setting can also offer some protection by surrounding the center stone with smaller diamonds.
