Oval engagement rings have emerged as a modern classic, chosen by celebrities including Lady Gaga, Phoebe Tonkin, Hailey Bieber, and Kourtney Kardashian. The cut features a rounded, elongated shape similar to round diamonds but with added length. Jewelers highlight its flattering effect on the hand and versatility in settings.
Oval diamonds are fancy-shaped stones with rounded edges and an elongated appearance. They share the brilliant faceting of round cuts, maximizing shine, while their length-to-width ratio makes them appear larger on the finger. Jenny Chung Seeger, founder of Eliette and No.3 Fine Jewelry, describes them as having 'all the sparkle of a classic, round diamond, but with a little more attitude.' The shape elongates the hand, offering a romantic yet modern silhouette with a sense of movement. The modern oval cut was refined in the late 1950s by cutter Lazare Kaplan, building on elongated shapes from the 18th century. Princess Diana's oval sapphire ring, now worn by Kate Middleton, exemplifies use in other gemstones. Evaluating ovals involves the 4Cs: cut, color, clarity, and carat. Since GIA does not grade cut for fancy shapes, focus on visual balance and symmetry. Chung Seeger advises prioritizing slightly higher color grades due to visibility in elongated forms, with clarity more forgiving and carat weight amplified by surface area. Settings vary widely: solitaires for minimalism, side stones or halos for added shine, bezels for protection, or east-west orientations for contemporary looks. Ideal length-to-width ratio is 1.4 to 1.5 per GIA; more elongated feels dramatic, fuller proportions classic. Minimize the bow-tie effect—a darkened central area—by observing light performance. Lab-grown ovals allow experimental proportions and larger sizes, while natural ones adapt to crystal inclusions.
