However, if you know what features are important to you (e.g., sparkle, fire, brilliance, size, durability, etc.), you can more easily narrow down the diamond shape that is right for your taste and lifestyle.

Diamond Shape Gemstone Characteristics Practical Considerations
Emerald Emerald-shaped diamonds are sophisticated, emitting mirror-like reflections rather than intense sparkle. They are typically rectangular with clipped corners. Emerald-shaped diamonds can appear larger than round cuts of the same carat weight. They have a clean, glass-like appearance making them look luxurious. Because they have clipped corners, these diamond shapes are less likely to chip. Settings include solitaire, three-stone, or vintage designs. They often cost less than round brilliants and are ideal for buyers who prefer clarity and structure.
Oval Oval-shaped diamonds feature strong sparkle with a softer light pattern than round brilliants. Their elongated shape makes them appear larger and gives a smooth, organic look while elongating the finger. Rounded edges make them resistant to chipping. They work well in halo, hidden halo, bezel, and three-stone settings. Extremely popular for engagement rings with an elegant, modern feel.
Radiant Radiant-shaped diamonds blend the structure of emerald cuts with the sparkle of round brilliants. Known for a “crushed ice” appearance, they feel bold and contemporary while hiding inclusions well. Often priced below rounds. Durable with no sharp corners, making them ideal for daily wear. Best in solitaire, hidden halo, pavé, or three-stone settings.
Marquise Because of its elongated shape, a marquise diamond appears larger than other shapes and creates a finger-lengthening effect. It offers strong sparkle with a bold, dramatic look. Best set with v-prongs or bezel for protection. Works well in solitaire styles. Ideal for bold aesthetics but less suited for very active lifestyles.
Cushion Cushion-shaped diamonds have a soft, pillow-like shape with a romantic feel. Known for vivid fire and warmth, they offer a plush, dimensional look. Best in halo, vintage, or three-stone settings. Require secure settings due to rounded corners. Typically more affordable than rounds and great for romantic styles.
Round Round brilliant diamonds offer maximum sparkle with 57–58 facets optimized for light reflection. They appear balanced and timeless. Highly durable with no corners. Works in all settings and is the most popular, making it easy to resell or upgrade.
Pear Pear-shaped diamonds combine round brilliance with a tapered point. They offer strong sparkle and a unique, elegant silhouette. Can be worn tip up or down for different effects. Best in solitaire or halo settings. Regular cleaning helps maintain brilliance.
Princess Princess-shaped diamonds have a square shape with brilliant faceting, offering strong sparkle and a modern look. Corners should be protected with v-prongs or bezel settings. Popular and more affordable than rounds, with strong resale appeal.
