Oval Cut Engagement Rings

An oval cut diamond is an elongated, rounded shape that combines the brilliance of a round cut with a unique, sophisticated outline. It is known for its elegant appearance and ability to make fingers look longer and more slender.

• Brilliance: Look for a diamond with excellent or very good cut grades to ensure maximum sparkle.
• Symmetry: Ensure the diamond has even, symmetrical facets and a well-proportioned shape.
• Bow-tie Effect: A slight bow-tie effect (a dark area across the center) is normal, but avoid diamonds with a prominent or distracting bow-tie.

Oval-cut diamonds offer a unique sparkle that, while different, is comparable to the round brilliant diamond. Both cuts feature a brilliant facet pattern, enhancing their ability to reflect light. However, the oval cut's elongated shape can create a larger surface area, resulting in a "bow-tie" effect, where light and dark areas form across the diamond. This effect adds character and depth to its sparkle. Although round brilliant diamonds typically maximize brilliance due to their symmetrical shape, oval-cut diamonds provide a distinctive and elegant alternative with comparable fire and scintillation.

An oval cut diamond has a rounded shape with no pointed ends, while a marquise cut diamond has pointed ends and a more elongated, boat-like shape. The facet arrangements also differ slightly, affecting how light reflects within the stone. While both cuts have brilliant faceting, the marquise cut can sometimes show more variation in light performance due to its pointed ends.

A well-cut oval diamond will have even, symmetrical facets, good polish, and a balanced length-to-width ratio. It should reflect light evenly across the surface and show minimal bow-tie effect.

Oval-cut diamonds are unique due to their elongated shape, which makes them appear larger than other cuts of the same carat weight. They offer excellent brilliance and fire with a brilliant-cut facet pattern and often feature a subtle bow-tie effect that adds character. Their versatile shape complements various ring styles and finger shapes, creating a flattering, slenderizing effect that makes them one of the most popular choices for engagement rings.
