Oval vs Round Diamond
Round and oval are two of the most popular diamond shapes, but they look and cost very differently. Compare brilliance, price and finger flattery to choose the right one.
Round vs Oval at a Glance
The round brilliant is the classic, with 58 facets engineered for maximum fire. The oval cut is an elongated round, offering similar sparkle with a larger-looking silhouette and a modern, slender profile. Both are excellent, safe choices for an engagement ring.
Because oval rough is wasted less than round rough, an oval of the same carat usually costs 20-30% less, making it one of the smartest value shapes available.
Comparison Table
| Factor | Round Brilliant | Oval Cut |
|---|---|---|
| Brilliance | Highest | Very high |
| Price per carat | Highest | 20-30% lower |
| Finger look | Classic, balanced | Elongates and slims |
| Style | Timeless | Modern, flattering |
| Risks | None significant | Bow-tie effect |
How to Decide
Choose round if you want the ultimate brilliance and a timeless silhouette. Choose oval if you want a larger look per carat, a finger-elongating shape, or a more contemporary style. When buying an oval, inspect the bow-tie effect and choose an excellent cut with a length-to-width ratio of 1.30-1.45.

Why are oval diamonds cheaper than round?
An oval is cut from rough with less waste than a round brilliant, so the price per carat is typically 20-30% lower for the same quality.
Does an oval look bigger than a round of the same carat?
Yes. Because the oval is elongated, it covers more finger surface and appears larger than a round of equal carat weight.
What is the best oval cut ratio?
A length-to-width ratio of 1.30 to 1.45 gives a balanced, elegant oval. Ratios above 1.5 look thinner and more elongated.
