The Cushion Brilliant Cut Diamond

The Cushion Brilliant cut, often referred to as the 'pillow cut' due to its soft, rounded corners and cushion-like appearance, is a popular choice for diamond and gemstone jewelry. It offers a captivating blend of the classic round brilliant's sparkle and the romantic, antique charm of older cuts.

Key Features

The Cushion Brilliant cut is characterized by several distinctive features that contribute to its appeal:

• Shape: Typically square or rectangular with rounded corners, resembling a cushion.
• Facets: Similar to a round brilliant cut, it possesses numerous facets designed to maximize brilliance and fire. Modern Cushion Brilliant cuts often have 58 facets, though variations exist.
• Brilliance and Fire: The cut is engineered to reflect light brilliantly, producing flashes of white light (brilliance) and colorful spectral hues (fire). The rounded corners can diffuse light slightly more than a square shape, leading to a softer, yet still impressive, sparkle.
• Scintillation: This refers to the play of light and dark areas as the gem moves. Cushion Brilliant cuts exhibit dynamic scintillation, creating lively flashes that draw the eye.
• Depth: The depth percentage of a Cushion Brilliant cut can vary. A well-cut stone will have optimal depth to allow for maximum light return.
• Outline: The defining rounded corners distinguish it from other square or rectangular cuts like the Princess or Emerald.

Origin and History

The roots of the Cushion cut can be traced back to the early 18th century with the development of the 'Old Mine Cut'. This early iteration was more rectangular and less symmetrical than today's Cushion Brilliant, featuring a high crown and a small culet. It was the dominant shape for diamonds during the Georgian and Victorian eras. As cutting technology evolved, so did the shape. The 'Cushion Brilliant' emerged as a modification of the Old Mine Cut, incorporating principles of the modern round brilliant cut to enhance its sparkle and symmetry, leading to the shape we recognize today.

Types / Variations

While the Cushion Brilliant is a specific cut, there are variations that cater to different aesthetic preferences:

• Cushion Modified Brilliant: This is the most common modern variation. It features an extra row of facets on the pavilion, which can enhance its fire and sparkle, sometimes giving it a more contemporary, 'crushed ice' appearance compared to the traditional Cushion Brilliant's larger flashes of light.
• Cushion Square Brilliant: These stones are cut to be nearly perfect squares, with length-to-width ratios very close to 1.00.
• Cushion Rectangular Brilliant: These have a discernible rectangular shape, with length-to-width ratios greater than 1.00.
• Antique Cushion Brilliant: These often retain characteristics of the Old Mine Cut, such as a slightly more elongated shape, a visible culet, and a different facet pattern that produces broader flashes of fire and light, often with a desirable antique or vintage look.

How It's Made

Crafting a Cushion Brilliant cut diamond involves meticulous precision. The process begins with a rough diamond. Gem cutters carefully map out the facets, considering the rough diamond's natural crystal structure and inclusions. The stone is then sawn or cleaved, and precisely ground and polished to create the specific angles and proportions of the Cushion Brilliant cut. The number and placement of facets are critical to achieving the desired balance of brilliance, fire, and scintillation. Modern technology aids in achieving greater accuracy and symmetry than was possible with older methods.

Grading & Quality Standards

Like other brilliant cuts, Cushion Brilliant diamonds are graded based on the '4 Cs':

• Carat: The weight of the diamond.
• Cut: For Cushion Brilliants, this refers to the precision of the facet angles, proportions, and finishing. A well-executed cut maximizes light performance. While the Gemological Institute of America (GIA) does not provide a specific 'cut' grade for fancy shapes like the Cushion Brilliant, it provides detailed plotting of the diamond's proportions and finish, allowing buyers to assess its quality. Independent labs may offer cut grades.
• Color: The absence of color. For Cushion Brilliants, color grades range from D (colorless) to Z (light yellow or brown). Many prefer diamonds in the G-J range for a good balance of appearance and price.
• Clarity: The absence of internal inclusions and external blemishes. Grades range from Flawless (FL) to Included (I3). For Cushion Brilliants, minor inclusions are often less noticeable due to the cut's brilliance and rounded corners, making VS or SI clarity grades a popular choice.

Buying Guide

When considering a Cushion Brilliant cut diamond or gemstone, keep these factors in mind:

• Shape Preference: Decide if you prefer a more square or rectangular outline. Look at the length-to-width ratio. A ratio of 1.00 is perfectly square, while ratios around 1.10 to 1.20 create a pleasant rectangular shape.
• Sparkle Type: Do you prefer the larger, distinct flashes of light of a traditional Cushion Brilliant, or the more numerous, smaller flashes and 'crushed ice' effect of a Cushion Modified Brilliant?
• Setting: Cushion cuts look stunning in various settings. Solitaire settings highlight the stone's beauty. Pave or halo settings can add extra sparkle and make the center stone appear larger. Be mindful that the rounded corners can be more prone to chipping than sharper corners, so protective settings like bezels or four-prong settings are often recommended.
• Budget: Cushion cuts are generally more affordable than round brilliant cuts of comparable size and quality, as they can be cut from rough diamonds with less waste.
• Certification: Always seek out diamonds with a reputable grading report from labs like GIA or AGS, especially for significant purchases.

Price Range & Value Factors

The price of a Cushion Brilliant cut diamond is influenced by the same factors as other diamonds, primarily the 4 Cs. However, some nuances apply:

• Cut Quality: While not always formally graded by major labs, the quality of the cut significantly impacts price. A diamond cut for optimal brilliance and fire will command a higher price.
• Shape Ratios: A perfectly square Cushion Brilliant might be priced differently than a rectangular one, depending on market demand.
• Market Trends: As a popular shape, Cushion Brilliants generally hold their value well.
• Comparison to Round Brilliant: Cushion Brilliant cuts are typically priced lower than round brilliant cuts due to more efficient rough diamond yield. This allows buyers to potentially get a larger stone for the same budget.

Care and Maintenance

Caring for a Cushion Brilliant cut gemstone is similar to caring for other precious gems:

• Cleaning: Gently clean your jewelry with a soft brush, warm water, and mild dish soap. Rinse thoroughly and dry with a lint-free cloth. Avoid harsh chemicals or abrasive cleaners.
• Storage: Store your jewelry in a soft pouch or a lined jewelry box to prevent scratches and damage. Keep it separate from other pieces to avoid abrasion.
• Professional Inspection: Have your jewelry professionally inspected and cleaned periodically by a jeweler. They can check the security of the setting and ensure the gemstone is clean and free from damage.
• Protection: Be mindful of the rounded corners. While durable, they can be susceptible to chipping if subjected to hard impact. Consider protective settings for everyday wear.

Pros and Cons

Pros:

• Unique Charm: Offers a romantic, vintage appeal distinct from the modern round brilliant.
• Excellent Sparkle: Provides significant brilliance and fire, especially the modified versions.
• Value: Generally more affordable per carat than round brilliant diamonds.
• Versatility: Looks beautiful in a wide range of settings and jewelry styles.
• Inclusion Masking: The brilliance and facet arrangement can help mask minor inclusions.

Cons:

• Corner Vulnerability: Rounded corners can be slightly more prone to chipping than sharply pointed corners.
• Cut Variation: The wide range of acceptable proportions means cut quality can vary significantly; careful selection is needed.
• Less Standardized Grading: Lack of a universal 'cut' grade from major labs requires more buyer diligence.

Famous Examples

While specific famous Cushion Brilliant diamonds might be less documented than round brilliants, the shape itself has graced many significant pieces of jewelry throughout history, often falling under the 'Old Mine Cut' or 'Antique Cushion' classification. Many celebrity engagement rings feature Cushion cut diamonds, showcasing their enduring popularity.

FAQs

What is the difference between a Cushion Brilliant and a Cushion Modified Brilliant?

The main difference lies in the facet structure on the pavilion (the bottom part of the diamond). A Cushion Modified Brilliant typically has an extra set of facets on the pavilion, resulting in a more dispersed, 'crushed ice' appearance with numerous small flashes of light. A traditional Cushion Brilliant often exhibits larger, more distinct flashes or 'fire'.

Are Cushion Brilliant cuts more expensive than round brilliants?

Generally, Cushion Brilliant cuts are less expensive per carat than round brilliant cuts of equivalent quality. This is because they can often be cut from rough diamonds with less waste, making them a more economical choice for achieving significant size.

Which is better for an engagement ring, Cushion Brilliant or Round Brilliant?

This is a matter of personal preference. Round brilliants are known for maximizing sparkle and are the most traditional choice. Cushion Brilliants offer a unique blend of sparkle, romance, and vintage charm. Both are excellent choices, depending on your aesthetic.

How do I choose the right proportions for a Cushion Brilliant cut?

Consider your preference for shape: a length-to-width ratio near 1.00 results in a square shape, while ratios from 1.05 to 1.20 create a more elongated, rectangular look. Examine the diamond's appearance to ensure you find the balance of brilliance and fire that appeals to you.
