What an Oval Cut Diamond Actually Looks Like?
The oval brilliant is an elongated brilliant cut, typically 56 to 58 facets with a rounded, continuous outline and no corners or points. Its length-to-width ratio typically runs from 1.30 to 1.70, with ratios around 1.35–1.50 producing the most balanced, universally flattering silhouette and ratios above 1.60 producing a more dramatically elongated look that suits longer fingers particularly well.
Oval delivers the largest face-up area per carat of any brilliant cut shape. A 1.5ct oval covers measurably more finger surface than a 1.5ct round, which is the primary reason it overtook round as the most-searched engagement ring shape in several major markets from 2022 onward. The bow-tie effect is inherent to the oval cut: a darkened zone across the centre of the stone caused by light leakage through the elongated middle facets. Every oval has some degree of bow-tie; the variable is severity, from imperceptible to strongly visible, determined by the specific cut proportions of that individual stone.
How Oval Cuts Wear and What We Source?
Oval's rounded outline makes it one of the more durable brilliant cuts for daily wear, with no corners or pointed tips to chip, and a low-profile setting sits comfortably without snagging. The finger-flattering elongation effect is real and consistent: the oval outline draws the eye along the length of the finger rather than across it, which makes most finger shapes appear longer and more slender.
The bow-tie is the honest tradeoff every oval buyer needs to factor in before purchasing. A severe bow-tie, a strongly dark band across the centre of the stone visible in normal lighting, cannot be corrected after cutting, and it is not always detectable from a single static photograph. Viewing a 360° video of the specific stone before purchase is the only reliable way to assess bow-tie severity.
At EthicStone, we source VS2 clarity or better for every oval we set. Inclusions show more readily in elongated brilliants than in round because the elongated facet arrangement concentrates light differently across the stone. Cut is sourced to Excellent or Ideal, color to D–G for lab grown diamond and D–F equivalent for moissanite. Metal options across 925 sterling silver, 10k, 14k, and 18k gold in white, yellow, and rose, and platinum, all hand-finished in our workshop.
What We Look for in an Oval Cut Stone?
Oval is one of the most variable brilliant cuts to source well. The same IGI cut grade can cover a wide range of actual proportions in an oval, unlike a round, where table and depth percentages are tightly standardised. The result is that two Excellent-grade ovals can look meaningfully different face-up, which is why our sourcing process for ovals goes beyond the grade label.
- Cut and proportions: Excellent or Ideal cut grade as a floor. Beyond the grade, we assess L/W ratio (targeting 1.35–1.50 for standard orders unless specified otherwise), bow-tie severity (imperceptible to minimal only), and shoulder curvature — flat shoulders produce a shape that reads more rectangular than oval face-up.
- Color: D–G for lab grown diamonds. D–F equivalent for moissanite. Color tends to concentrate slightly at the tips of elongated shapes — sourcing to D–G keeps the tips in the colorless to near-colorless range.
- Clarity: VS2 or better as a quality floor. Inclusions are more visible in elongated brilliants than in round ones at the same clarity grade because the elongated facet arrangement distributes light differently, making inclusions easier to detect face-up.
- Certification: Every lab grown diamond arrives with its IGI certification report. You receive the original certificate with your ring.
- Setting and metal standards: Prongs in solid 925 sterling silver, 10k, 14k, or 18k gold, or platinum — four-prong or six-prong configuration with prongs positioned at the north, south, east, and west points to secure the oval outline without obscuring the elongated silhouette. Hand-finished by our workshop setters.
You specify the carat range and design. We assess each oval individually against these standards, including bow-tie severity, so the stone that arrives performs as well face-up as it does on the certificate.
