Shapes of Diamonds

The world of diamond cuts is vast and varied, with each cut possessing its unique beauty and appeal. In this article, we will explore the characteristics of the most popular diamond cuts and provide tips on how to select the perfect diamond based on its cuts and proportion ratios.

Classic Round Brilliant Diamonds

The Round Brilliant cut diamond is a popular choice, making up about 75% of all diamond sales according to the Gemological Institute of America (GIA). Invented in 1919 by Marcel Tolkowsky, this diamond cut features 57 facets in a round shape, designed to maximize sparkle and beauty.

Tolkowsky spent years researching and calculating the perfect cut to achieve an amazing level of sparkle. When choosing a round brilliant diamond, look for one with an "excellent" cut grade. At Ajediam, we like our diamonds to have a table ratio between 58% and 63%.

Emerald Diamonds

The emerald cut diamond is a captivating blend of elegance, sophistication, and contemporary style. Its rectangular shape, beveled corners, and step-like facets parallel to the girdle give it a distinct, modern appeal. Perfect for those seeking to highlight the natural allure of their diamond, the emerald cut showcases the stone's clarity, color, luster, and transparency in an impressive manner.

This cut's large, open table and elongated facets allow more light to permeate and reflect back, creating a mesmerizing "hall of mirrors" effect. However, due to its distinctive cut, it magnifies any flaws or inclusions, which should ideally be minute and located at the edges, not under the table. The ideal length-width ratio for this cut is 1.40, though unique specimens with a ratio of about 2.00 are highly sought after by discerning customers, often fetching a premium price.

Asscher Diamonds

Embodying the timeless allure of the 1920s, the Asscher cut diamond, also celebrated as the Square Emerald cut, is a piece of history you can adorn. Patented in 1902 by the Asscher Brothers of Holland, this cut invites a mesmerizing peek into the diamond's soul, courtesy of its profound, open lines and captivatingly clear depth.

When you're choosing your perfect Asscher cut, remember that perfection lies in its squarish charm, go for the dimension of a perfect square. This cut is a clear window to the heart of your diamond, revealing any heavier inclusion. Thus, diamonds of superior clarity are your perfect match. Seek out those quintessential proportions, a total depth ratio of 58 to 63, to truly capture the unique enchantment of the Asscher cut.

Cushion Diamonds

The Cushion cut diamond, a romantic meld of the Old Mine and Oval cuts, is a testament to timeless allure and classic elegance. Its antique shape has been charming hearts for generations, encapsulating a sense of love that transcends time.

When selecting your Cushion cut diamond, the quintessential choice is the 1 square ratio, a common yet captivating option. However, if you're in pursuit of rarity and are willing to venture into the higher price bracket, the elongated models with a 1.3-1.6 ratio could be your unique gem. Aim for a total depth ratio of 58-63 to ensure the stone's brilliance. And remember, finding the perfect Cushion with excellent make can be a quest; sometimes, when the market falls short of a Cushion with enough vivacity, we recommend considering a brilliant cushion. After all, your diamond should not just be a stone, but a sparkling embodiment of life.

Marquise or Navette Diamonds

Steeped in romantic legend, the Marquise or Navette cut is said to have been commissioned by Louis XIV, inspired by the smile of his mistress, the Marquise de Pompadour. The grandeur and brilliance of the Marquise cut are a testament to its meticulous crafting, showcasing precise proportions, absolute symmetry, and a polished finish that emits an unmatched fire.

While choosing your Marquise diamond, be mindful of the 'Butterfly effect,' a characteristic of this cut. The most pleasing Marquise cuts often present a slightly elongated shape, with a standard length ratio of 2.0. While some fear the potential fragility of its sharp edges, rest assured that it is a rare occurrence and not a significant concern. What truly matters is the balance in its cut; it should be neither too plump nor too flat, with a total depth ratio between 58 and 63. This will ensure the diamond retains its distinctive fire and brilliance, a mark of the Marquise.

Oval Diamonds

Capturing the essence of history and modern innovation, the Oval Cut diamond brings forth a unique brilliance. Tracing its lineage back to the 19th-century Koh-i-Noor diamond, its modern identity was shaped by Lazare Kaplan in 1957. Kaplan, known for his transformative magic on diamonds, introduced a new era of radiance with this cut.

When choosing your Oval Cut, be aware of the 'Butterfly effect'. The preferred length ratio is 1.30 but a more elongated ratio of 1.4 often attracts collectors and commands higher prices. Seek a balanced cut with a depth ratio between 58 and 63. This ensures your Oval Cut diamond truly sparkles, echoing its rich history and contemporary charm.

Pear or Pendeloque Diamonds

Indulge in the captivating elegance of a Pendeloque or Pear-shaped diamond, a cut steeped in historical richness and a beloved choice in the world of diamonds. This unique shape possesses the remarkable ability to flatter the finger, creating an illusion of slender grace. Moreover, its dazzling play of light and reflection elevates it to a true statement piece.

As you embark on your quest for the perfect Pear Shape diamond, set your sights on those with a length ratio ranging from 1.60 to 1.70. These elongated beauties not only boast aesthetic appeal but also hold a coveted status in the market. Strive for an ideal total depth of around 58-63%, ensuring a well-balanced cut that emanates life and brilliance with every movement. Let the Pendeloque or Pear-shaped diamond become the centerpiece of your jewelry collection, showcasing the epitome of elegance and timeless allure.

Radiant Diamonds

Introduced in 1977 by Henry Grossbard, the Radiant cut diamond seamlessly marries the sophistication of an Emerald step cut with the scintillation of a Round brilliant cut. Boasting an impressive 70 facets meticulously crafted to maximize its luminosity, the Radiant cut diamond is a true testament to the artistry of diamond cutting.

When it comes to the Radiant cut, seekers of exceptional beauty often lean towards longer models rather than thicker cuts. While the allure of a square Radiant cut may not be as widely appreciated, the true charm lies in the elegant proportions ranging between 1.25 to 1.35. Aficionados may cherish lengthier Radiant cuts, as they possess a rarity that demands a premium price, however, those can be quite elusive, particularly if you desire matching pairs. Embrace the mesmerizing allure of the Radiant cut and bask in its enchanting brilliance that captures hearts and ignites desires.

Heart Diamonds

The Heart shape diamond, an embodiment of romance and sentimentalism, stands as the ultimate symbol of love. While it may not be a conventional cut, its unmistakable shape holds immense appeal, making it a coveted choice for many.

To fully appreciate the mesmerizing beauty of a Heart shaped diamond, it is crucial to find the perfect balance in its proportions. When selecting a Heart shape diamond, steer clear of lengthier models and aim for length ratios between 0.85 and 0.95 and an ideal total depth of around 58-63%. These ranges ensure a pleasing symmetry and play a vital role in capturing its brilliance and radiance. Choose wisely, and let the Heart shaped diamond become an enduring symbol of your love story.
