Choosing the best natural diamond cut for an engagement ring often comes down to a balance of personal preference, desired sparkle, and how large the diamond appears. Here’s a brief overview of popular and highly regarded natural diamond cuts:
- Round Brilliant Cut:
• Why it’s popular: This is by far the most popular diamond cut, and for good reason. It’s meticulously designed with 57 or 58 facets to maximize brilliance (white light reflection), fire (flashes of color), and scintillation (sparkle as the diamond moves).
• Look & Feel: Classic, timeless, and offers the most sparkle of all cuts.
• Consideration: Due to its optimal light performance, it can sometimes appear smaller for its carat weight compared to elongated shapes, as a significant portion of its weight is in its depth. - Oval Cut:
• Why it’s popular: A sophisticated and increasingly popular choice, the oval offers similar brilliance to a round brilliant but with an elongated shape.
• Look & Feel: Elegant, can make fingers appear longer and slenderer, and often looks larger than a round diamond of the same carat weight due to its larger surface area.
• Consideration: Can sometimes exhibit a “bow-tie effect” (a dark area across the center) if not cut well.

- Cushion Cut:
• Why it’s popular: This cut combines a square or rectangular shape with rounded corners, giving it a soft, “pillow-like” appearance. It’s often chosen for its romantic and vintage appeal.
• Look & Feel: Offers a unique blend of brilliance and a softer, warmer sparkle, sometimes described as a “crushed ice” effect.
• Consideration: Can vary significantly in facet patterns, leading to different visual effects. Some may prefer the “chunky” facet pattern over the “crushed ice” look. - Princess Cut:
• Why it’s popular: A modern and popular choice, the princess cut is typically square (though it can be rectangular) with sharp, pointed corners. It offers excellent brilliance.
• Look & Feel: Contemporary, edgy, and very sparkly, second only to the round brilliant in light performance.
• Consideration: The pointed corners can be prone to chipping if not protected by a secure setting. - Emerald Cut:
• Why it’s popular: Known for its understated elegance and “hall-of-mirrors” effect. It’s a “step-cut” diamond, meaning its facets are long and rectangular, running parallel to the girdle.
• Look & Feel: Sophisticated, sleek, and emphasizes clarity and the diamond’s natural color. It offers less sparkle than brilliant cuts but has a distinct, captivating depth. It can also make fingers appear longer.
• Consideration: Because of its large, open table, inclusions and color are more visible, so higher clarity and color grades are generally recommended.

- Pear Cut:
• Why it’s popular: A distinctive “teardrop” shape that combines the brilliance of a round with the elongated elegance of a marquise.
• Look & Feel: Unique, elegant, and can also make the finger appear longer. Offers good brilliance.
• Consideration: Like the oval, it can sometimes have a bow-tie effect. The pointed tip should be protected in the setting. - Radiant Cut:
• Why it’s popular: A versatile cut that combines the rectangular or square shape of an emerald cut with the brilliant faceting of a round.
• Look & Feel: Offers exceptional brilliance and fire in a rectangular or square shape, providing a balance of elegance and sparkle.
• Consideration: Can also exhibit a bow-tie effect if not cut well.
Key Factors to Consider Beyond Shape:
• Cut Quality: This is the most crucial factor for a diamond’s sparkle. A well-cut diamond, regardless of its shape, will always shine more brilliantly than a poorly cut one, even if other factors like carat weight, color, and clarity are higher. Look for excellent or very good cut grades from reputable grading labs like GIA or AGS.
• Personal Style: The “best” cut is ultimately the one that resonates most with your personal aesthetic and the style of the wearer.
• Budget: Some cuts (like round brilliants) tend to be more expensive per carat due to demand and the amount of rough diamond lost during cutting, while others (like marquise or oval) can appear larger for the same carat weight, offering good value.
No matter the cut, always prioritize a diamond with an excellent or very good cut grade to ensure maximum brilliance and beauty.
