An elongated cushion cut diamond is a variation of the traditional cushion cut, featuring a rectangular or oval shape with rounded corners. This elongated silhouette offers a modern twist on a classic cut, combining vintage charm with a sleek, elongated appearance.

An elongated cushion cut diamond is a variant of the classic cushion cut, characterized by its stretched, rectangular shape which differentiates it from the more usual square or rounded cushion cut diamonds. This cut maintains the pillow-like appearance of traditional cushion cuts, which is a combination of a square cut with rounded corners, but it has a length-to-width ratio that extends beyond the classic range. These proportions give the stone an elegant, elongated look that can accentuate the finger when set in a ring.

We consider the elongated cushion cut as a
sophisticated choice for those seeking a unique spin on the timeless appeal of cushion cut diamonds. While the classic cushion cut has a ratio of 1:1 to 1.05, elongated variations typically range from a ratio of 1.15 upwards, creating a more rectangular appearance. In the market, you will find these diamonds to be less common than their traditional counterparts, making them a distinctive selection.

When selecting an elongated cushion cut diamond, we emphasize the importance of cut quality, which directly influences the stone’s brilliance and overall appearance. A well-cut elongated cushion diamond with a higher length-to-width ratio will exhibit a distinguished profile and captivating sparkle that makes it a desirable choice for engagement rings and other elegant jewelry pieces.

Understanding the Elongated Cushion Cut Diamond


Elongated cushion cut diamonds exhibit a grace that combines the classic with the contemporary. Our focus is on the importance of cut quality and its unique appeal.

Cut Quality and Dimensions

Elongated cushion cut diamonds are discernible by their length-to-width (L/W) ratios. Typically, a ratio greater than 1.15 indicates an elongated shape, with optimal L/W ratios over 1.19 enhancing the stone's elegance. Such dimensions provide a flattering, slender appearance compared to the traditional cushion cut. We assess cut quality meticulously, as it directly influences the diamond's brilliance and overall visual appeal.

Relevant Dimensions For Elongated Cushion Cut Diamonds

  • L/W Ratio: Greater than 1.15 for a noticeably elongated shape.
  • Optimal L/W Ratio: Above 1.19 for a balance between elongation and sparkle.

The Appeal of Elongated Cushion Cut

The elongated cushion cut possesses a distinct charm attributed to its stretched silhouette. This shape offers a modern twist on the classic cushion cut, maintaining the soft, rounded corners but with a more pronounced rectangular outline. It caters to those seeking a fusion of vintage style and the sleekness associated with longer lines. Our preference for these diamonds is due to their rarity and the sophisticated flair they add to any piece of jewelry.

Elongated Cushion vs. Traditional Cushion Cut

The traditional cushion cut diamond is known for its soft, pillow-like appearance with rounded corners and a square to slightly rectangular shape. In contrast, the elongated cushion cut tends to have a more pronounced rectangular shape, affording it a distinctly different aesthetic. The key differences include:

  • Aspect Ratio: Traditional cushion cuts generally have a length-to-width ratio closer to 1.0, indicating a squarer shape, while elongated cushions boast ratios above 1.19, giving them a more stretched appearance.
  • Visual Impact: Elongated cushion cuts often appear larger due to their extended shape, even when they have the same carat weight as a traditional cushion cut.

Elongated Cushion Cut vs. Other Diamond Shapes

When compared to other diamond shapes, elongated cushion cuts offer a unique blend of classic and modern appeal:

  • Round Cut: Known for its brilliance, round cut diamonds are the benchmark for sparkle but lack the elongated cushion's vintage flair.
  • Princess Cut: This square shape with pointed corners offers a contemporary feel but does not provide the gentle curves of an elongated cushion.
  • Radiant Cut: Similarities with elongated cushion cuts exist, as both shapes can have a rectangular silhouette; however, radiant cuts have a more vivid sparkle due to their facet pattern.
  • Emerald Cut: The emerald cut offers a clean rectangular form with linear facets that create a hall-of-mirrors effect, contrasting with the softened corners and chunky facets of elongated cushion cuts.
  • Oval Cut: Oval diamonds share a similar lengthening effect on the finger but differ with a more uniform, continuous curve around the entire stone.

We see that each shape holds its own special attributes, and the choice between them often rests on personal preference for appearance and style.

The Role of Faceting in Aesthetics

In our exploration of elongated cushion cut diamonds, we understand that the facets play a pivotal role in defining the stone's visual appeal. Each facet acts as a tiny mirror, reflecting the interplay of light within the diamond, directly influencing its brilliance, fire, and scintillation.

Faceting Pattern and Brilliance

Faceting pattern refers to the geometric layout of the surfaces on a diamond. Elongated cushion cut diamonds, known for their stretched appearance and rounded corners, have a faceting pattern that is designed to maximize the stone's brilliance—the amount of white light reflected back to the viewer. It's a blend of patterns derived from the classic cushion cut, with larger facets added to improve their ability to reflect light. With a well-executed faceting pattern, an elongated cushion cut diamond will boast a mesmerizing display of light, creating a captivating visual effect that emphasizes its length and unique shape.

Fire and Scintillation in Elongated Cushion Cuts

Fire refers to the rainbow colors that emerge from within a diamond as it disperses light. Contrastingly, scintillation is the sparkle a diamond exhibits when moved in the light. For elongated cushion cuts, these qualities are essential to its aesthetic. The elongated shape paired with the diamond's faceting allows for a beautiful display of fire throughout the stone. However, it's important to note that the presence and visibility of fire and scintillation are deeply influenced by the precision of each facet cut. A meticulously cut elongated cushion will present a dance of fiery flashes and dynamic sparkle that enhances its elongated silhouette and contributes to its overall beauty.

Choosing the Right Setting for Elongated Cushion Cut Diamonds

When selecting a setting for an elongated cushion cut diamond, we aim to enhance both the stone's unique shape and its brilliance. The right setting not only secures the diamond but also complements its proportions and maximizes its visual appeal.

Halo Engagement Ring Settings

A halo setting can magnify the presence of an elongated cushion cut diamond by encircling it with smaller diamonds. This creates a stunning visual effect that emphasizes the stone's shape and increases its overall sparkle. Our main considerations for a halo setting include:

  • Symmetry: Ensuring the halo aligns perfectly with the elongated cushion cut for a harmonious look.
  • Proportion: Choosing a halo that complements the diamond's size without overwhelming it.

Solitaire and Three-Stone Settings

Solitaire settings are timeless, drawing all attention to the elongated cushion cut diamond. We prioritize:

  • Secure Prongs: Utilizing four to six prongs that securely hold the diamond in place while allowing ample light to enter.
  • Elevated Design: A raised setting to showcase the elongated shape without obscuring it.

For three-stone settings, the side stones can accentuate the elongated cushion cut's length and add depth to the ring's appearance. Our approach includes:

  • Side Stone Selection: Choosing side stones that match the elongated cushion cut's clarity and color.
  • Alignment: Ensuring the side stones are proportionate and align seamlessly with the central diamond for a balanced look.

In our discussion of elongated cushion cut diamonds, we recognize that color and clarity, as well as carat weight and finger coverage, are crucial. These characteristics play pivotal roles in both the appearance and the value of the diamond.

Color and Clarity Impact

Color in diamonds refers to the presence of a yellowish or brownish hue, with a grading scale that ranges from D (colorless) to Z (light color). For elongated cushion cuts, achieving a high color grade is beneficial for maintaining a brilliant appearance. Bolded bullet points for quick reference:

  • Color Grade: The less color, the higher the grade, and typically, the more desirable the diamond.
  • Clarity Grade: This denotes the presence of inclusions and blemishes. A higher clarity grade indicates fewer visible imperfections.

An elongated cushion cut diamond's larger table can make inclusions more noticeable, so a high clarity grade is often sought after to ensure a clean look.

Carat Weight and Finger Coverage

Carat weight represents the mass of the diamond, which correlates to size but doesn't directly translate to finger coverage. The elongated shape of cushion cuts, which stretches more across the finger, can give the illusion of a larger size. Here's how finger coverage and carat weight relate:

  • Carat Weight: The weight of the diamond measured in carats.
  • Finger Coverage: The area of the finger that the diamond occupies when viewed from above.

A higher carat weight in an elongated cushion cut diamond usually offers greater finger coverage, which is often desirable as it emphasizes the stone's presence on the hand without necessarily moving to a higher weight category.

Popularity and Trends

When evaluating elongated cushion cut diamonds, we must carefully consider their price and overall value, as well as understand the factors affecting their durability. It's important to balance the budget with the qualities of the gemstone to make a well-informed purchase.

Price and Value Determination

  • Budget: Establishing our budget is the first step. Elongated cushion cut diamonds can vary significantly in price depending on size, quality, and where they are purchased.
  • Price: Prices of elongated cushion cut diamonds are influenced by the 4 Cs—carat, clarity, color, and cut quality. A higher length-to-width ratio can sometimes command a premium due to its unique look.
  • Value: To ensure we are getting the best value, we should compare diamonds of similar quality across different vendors. A detailed inspection of certifications and the examination of the diamond's brilliance are essential.

Durability and Vulnerability Factors

  • Vulnerability: The corners of an elongated cushion cut diamond are its most vulnerable points. These should be protected by a well-designed setting that guards against chipping.
  • Durability: Although diamonds are the hardest natural substance, the cut and shape can affect durability. The elongated cushion cut's polished facets should be inspected for any signs of weakness that could make it susceptible to damage.

By navigating these practical elements with precision, we ensure that our choice in an elongated cushion cut diamond is both a sound investment and a durable, lasting symbol of beauty.

Gemstone Variations with Cushion Cuts

In the realm of colored gemstones, the allure of cushion cuts extends well beyond diamonds. We see sapphires and rubies adopting this sophisticated shape, offering a timeless appeal with their rich, vivid hues.

Sapphire and Ruby Cushion Cut Alternatives

Sapphires often exhibit an exceptional depth of color when cut into a cushion shape, allowing for a mesmerizing interplay of light. Our selection typically includes:

  • Blue Sapphires:
    • Traditional deep blue
    • Variations ranging from light pastels to almost midnight tones
  • Fancy Sapphires:
    • Yellow, pink, and other rare colors
    • Each presenting a unique character in a cushion cut

Cushion cuts maximize the brilliance and color saturation in sapphires, making every angle of the gemstone a delight to observe.

  • Deep, pigeon blood reds, a highly sought-after shade
  • Rich saturation that's evenly distributed across the facet structure
  • The balance between the gem's luster and its iconic red coloring

A cushion cut for rubies emphasizes the gem's transparency and can enhance its overall value, given how the cut allows for maximum light return and a robust display of its color.
