Explore Oval Cut Diamonds

Oval cut diamonds combine an elongated outline with brilliant-style faceting, giving them a different face-up shape from a round diamond while retaining a lively facet pattern. Ouros Jewels offers loose oval lab grown diamonds across different carat weights, color and clarity grades, proportions, and cutting styles.

The collection includes classic oval brilliants, longer oval proportions, colored diamonds, and selected specialty-faceted oval designs. Shoppers comparing other shapes can explore the broader lab grown diamonds collection.

How Oval Diamond Proportions Change the Look

The length-to-width ratio helps describe whether an oval diamond appears fuller or more elongated when viewed from the top.

A lower ratio creates a wider, rounder-looking oval, while a higher ratio produces a longer and narrower outline. Rather than treating one proportion as universally better, use the ratio to narrow the collection toward the appearance you prefer.

The diamond's actual measurements are also important because two oval diamonds with the same carat weight can have different face-up dimensions and proportions.

How to Evaluate an Oval Cut Diamond

Oval diamonds have several visual characteristics that are worth comparing alongside the grading report.

• Outline symmetry: The two sides and rounded ends should appear visually balanced.
• Bow-tie effect: A darker band may appear across the center of an oval diamond. Its strength varies between individual stones.
• Face-up spread: Compare the diamond's length and width rather than using carat weight alone to judge visible size.
• Color: Elongated diamonds may show color differently across the stone, so consider the overall face-up appearance.
• Clarity: Review the location and visibility of inclusions, not only the clarity grade.
• Facet pattern: Compare how evenly brightness and contrast are distributed across the stone.

Looking at the diamond's images or video alongside its measurements can help distinguish stones with otherwise similar grading specifications.

Classic, Elongated & Specialty Oval Diamonds

Oval diamonds can vary considerably even when they share the same basic outline.

Classic oval brilliant diamonds offer more balanced proportions, while elongated ovals create a longer and slimmer appearance. Ouros Jewels also carries selected specialty-faceted oval diamonds for shoppers looking for a less conventional facet pattern.

Depending on current inventory, colorless as well as brown and other colored oval lab grown diamonds may also be available.

IGI & GIA Certified Oval Lab Grown Diamonds at Ouros Jewels

Selected oval lab grown diamonds may be available with independent grading documentation from IGI or GIA, depending on the individual stone.

The report can provide stone-specific information such as carat weight, color, clarity, measurements, polish, symmetry, and other grading details according to the laboratory and report format.

Shoppers specifically looking for graded stones can explore certified loose diamonds.

Check the individual diamond listing to confirm the grading laboratory and documentation included with that stone.

North-South vs East-West Oval Diamond Settings

Oval diamonds are most commonly positioned north-south, with the longer axis running along the finger. An east-west setting rotates the stone horizontally, creating a wider appearance across the hand.

The orientation does not change the diamond itself, but it can significantly change how its proportions appear once set.

To compare how different oval proportions and orientations look in finished jewelry, explore oval engagement rings.

Oval Cut Diamond FAQs

Do oval diamonds look larger than round diamonds of the same carat weight?

Oval diamonds can show more visible surface area from the top because their weight is distributed across an elongated outline. The exact appearance depends on the individual diamond's measurements and proportions.

What causes the bow-tie effect in an oval diamond?

The bow-tie effect is a darker area that can appear across the center of an oval brilliant diamond because of how light interacts with its elongated facet arrangement. Its visibility varies from stone to stone.

Is a longer oval diamond better than a wider oval?

Neither proportion is automatically better. A wider oval creates a fuller outline, while a longer oval produces a more elongated appearance. The better choice depends on your preferred shape and eventual setting.

Are oval lab grown diamonds available in different colors?

Yes. Ouros Jewels offers colorless and colored oval lab grown diamonds, with specific colors depending on current inventory.

Can I buy an IGI or GIA graded oval lab grown diamond?

Eligible oval lab grown diamonds may be available with IGI or GIA grading documentation. Check the individual stone listing for the laboratory and report information.

Can an oval diamond be set horizontally?

Yes. An oval diamond can be set east-west with its long axis running across the finger rather than vertically. This changes the orientation and overall visual effect of the finished ring.
