The Ultimate Guide to the Elongated Cushion Cut Diamond

The world of diamond cuts is vast and varied, but few styles capture the imagination quite like the elongated cushion cut. This exquisite shape, a beautiful fusion of classic romance and modern elegance, has surged in popularity for its unique ability to offer both timeless appeal and a distinctive contemporary flair. Unlike its more traditional counterparts, the elongated cushion cut combines the soft, rounded corners of a classic cushion with a lengthened silhouette that creates an illusion of greater size and a more slenderizing effect on the finger. It is a cut for those who appreciate history but are not afraid to make a bold, personal statement.

The history of the cushion cut is a long and storied one, dating back to the late 17th century with what was originally known as the ‘mine cut.’ This antique predecessor was designed to maximize the brilliance of early diamond-cutting techniques, resulting in a shape with a high crown, small table, and a large culet. Over the centuries, this evolved into the ‘old mine cut,’ a forerunner with a squarish outline and softly rounded corners that is highly prized by vintage jewelry enthusiasts. The modern cushion cut as we know it emerged with advancements in technology and understanding of light performance. The ‘elongated’ variation is a more recent interpretation, stretching the classic square-rectangle ratio to create a more dramatic and graceful profile that appeals to contemporary tastes while retaining its antique soul.

So, what exactly defines an elongated cushion cut? It is characterized by several key features that set it apart. First and foremost is its rectangular shape with rounded corners, which is the defining characteristic of any cushion cut. The term ‘elongated’ specifically refers to its length-to-width ratio. While a classic cushion cut is nearly square, with a ratio of around 1.00 to 1.05, an elongated cushion cut typically has a ratio between 1.15 and 1.25. This subtle stretch makes all the difference, creating a more elegant and finger-flattering shape. The cut is also known for its facet pattern. Modern elongated cushions often have a ‘crushed ice’ appearance, where a larger number of smaller facets create a dazzling, intricate sparkle that differs from the clear, chunky facets of an emerald cut or the predictable pattern of a round brilliant.

When shopping for an elongated cushion cut diamond, several critical factors determine its beauty and value. Understanding these will empower you to make an informed choice.

• Cut Quality: This is the most important of the 4Cs for a cushion cut. A well-cut diamond will exhibit exceptional brilliance and fire. Look for a stone with good symmetry and polish. The term ‘cut’ here refers not to the shape, but to how effectively the diamond’s facets interact with light.
• Length-to-Width Ratio: This is a matter of personal preference. A ratio of 1.10 to 1.20 will offer a more moderate elongation, while ratios above 1.20 will appear more rectangular. It’s crucial to view different ratios in person or through high-quality videos to see which silhouette appeals to you most.
• Faceting Style: Elongated cushions can have different facet patterns. The ‘crushed ice’ look offers a glittering, multifaceted sparkle, while a ‘chunky’ or ‘antique’ facet pattern provides broader, more geometric flashes of light. Neither is superior; it purely depends on the visual effect you desire.
• Color and Clarity: Due to their facet structure, elongated cushion cuts can sometimes retain more color than a round brilliant diamond. Many choose a near-colorless grade (G-H) for a white appearance. Similarly, their complex faceting can help to conceal minor inclusions, so a VS2 or SI1 clarity grade can often be an excellent choice for maximizing size and value without compromising on eye-cleanliness.

Choosing the perfect setting is essential to showcasing the beauty of your elongated cushion cut diamond. The setting not only secures the stone but also enhances its character and complements its shape.

1. Solitaire Setting: A simple solitaire in yellow gold, white gold, or platinum is a timeless choice. It allows the unique shape and sparkle of the elongated cushion to take center stage without any distractions. A four-prong or six-prong setting will securely hold the diamond while letting in maximum light.
2. Halo Setting: A halo of smaller diamonds surrounding the central elongated cushion cut is an incredibly popular option. This design amplifies the diamond’s perceived size and adds an immense amount of extra sparkle. A halo can be crafted to follow the rectangular shape or can be a contrasting shape, like an oval, for added visual interest.
3. Three-Stone Setting: This design is rich with symbolism, representing your past, present, and future together. Flanking the elongated cushion cut with two smaller trapezoid or pear-shaped diamonds creates a balanced and glamorous look that further elongates the finger.
4. Vintage and Ornate Settings: Given its antique origins, the elongated cushion cut looks stunning in vintage-inspired settings. Intricate milgrain details, filigree work, and engraved bands can create a one-of-a-kind piece that feels both heirloom and contemporary.

It is only natural to compare the elongated cushion cut to other popular diamond shapes to understand its unique position. The round brilliant cut is the undisputed champion of brilliance and sparkle, known for its unmatched fire and technical perfection. In contrast, the elongated cushion offers a softer, more romantic and glittery brilliance. Compared to the emerald cut, which features a clean, linear, and hall-of-mirrors effect, the elongated cushion is all about a chaotic, dazzling sparkle. It is less formal and more playful than an emerald cut. When placed next to an oval cut, another popular elongated shape, the key difference lies in the corners. The oval’s completely curved silhouette offers a different kind of softness, while the elongated cushion’s rounded corners provide a distinct geometric charm that is both classic and unique.

Beyond its undeniable beauty, the elongated cushion cut offers several practical advantages. Its elongated shape is universally flattering, as it creates the illusion of a longer, slimmer finger. Furthermore, because it is not as common as the round brilliant cut, it often offers better value for money. You can frequently get a larger carat weight elongated cushion for the same price as a smaller round brilliant, allowing you to maximize the presence of your jewelry. Its blend of antique charm and modern lines also makes it incredibly versatile, pairing beautifully with a wide range of wedding band styles, from simple metal bands to more elaborate diamond-accented ones.

In conclusion, the elongated cushion cut diamond is a magnificent choice for anyone seeking a stone with personality, elegance, and a touch of historical romance. It stands out from the crowd without being overly ostentatious, offering a unique sparkle that is both soft and brilliant. By paying close attention to the cut quality, ratio, and setting, you can select an elongated cushion cut diamond that is not just a piece of jewelry, but a true reflection of your individual style—a timeless treasure that will be adored for a lifetime.
