Oval vs Elongated Cushion Diamond Compared
A continuous curve versus a rounded-square outline stretched long — how oval and elongated cushion actually differ, and how to choose.
Both oval and elongated cushion are elongated, "looks bigger than its carat weight" shapes currently in high demand — the difference is entirely in the outline.
The core visual difference
Oval is a single continuous curve with no corners at all. Elongated cushion keeps the cushion cut's signature soft, rounded corners on a longer, more rectangular body — see our oval and elongated cushion buying guides for the full detail on each. If you want a pure, unbroken curve, oval is the only one of the two that delivers it; if you want a softer echo of a square or rectangular outline, elongated cushion is the closer match.
Faceting style options
Oval is faceted in one broadly consistent brilliant style. Elongated cushion offers a genuine style choice within the shape itself — a bolder, chunkier facet pattern or a softer "crushed ice" pattern (see our crushed ice guide) — giving cushion buyers an extra decision oval doesn't really offer.
Bow-tie
Both shapes can show a bow-tie (see our bow-tie guide), though it's typically more pronounced and more commonly discussed on oval than on elongated cushion.
Antique association
Elongated cushion currently carries a stronger antique/vintage association in the market, often paired with Old Mine Cut-inspired settings (see our Old Mine Cut buying guide); oval reads as more contemporary and versatile across a wider range of setting styles.
Which to choose
Choose oval for the cleanest, most elongated look and the widest range of setting styles it pairs well with. Choose elongated cushion for a softer, more structured outline with a genuine antique-inspired character, and the added choice between chunky and crushed-ice faceting.
