Oval vs Cushion vs Round Diamonds
Round, oval and cushion diamonds can all be beautiful, but they create different visual effects and demand different inspection priorities.
| Factor | Round | Oval | Cushion |
|---|---|---|---|
| Outline | Circular | Elongated | Square/rectangular with rounded corners |
| Facet personality | Highly standardized brilliant | Modified brilliant; bow tie varies | Many facet patterns; broad-flash to crushed-ice looks |
| Cut evaluation | Most standardized | Requires more visual inspection | Requires more visual inspection |
| What to watch | Overall light performance | Bow tie, outline symmetry | Facet pattern, mushy areas, outline |
Choose round if…
You want a classic outline, a standardized cut framework and strong brilliant-style light performance.
Choose oval if…
You like elongation and face-up spread and are willing to compare several stones for bow-tie behavior and outline balance.
Choose cushion if…
You want soft corners and more personality in the facet pattern. Cushion appearance varies widely, which makes video comparison especially useful.
