The oval has quietly become the most requested alternative to the round, and the reasons are practical rather than fashionable. It uses brilliant faceting, so it sparkles like a round. It is elongated, so it covers more finger for the same weight and flatters the hand. And because cutting an oval wastes less rough, it costs less per carat.
The catch is that ovals receive no overall cut grade. You have to read the stone yourself. Two numbers and one visual check do almost all of it.
It looks bigger, and that is measurable
Weight is not size. A round carries much of its weight in depth, below the setting where nobody sees it. An elongated shape spreads the same weight across a larger surface facing up. In practice a well cut oval reads roughly a full size step larger than a round of identical weight — so a 1.20 carat oval sits on the hand about like a 1.50 carat round, at a lower price.
That is the whole commercial argument for the shape, and it holds.
The ratio decides the personality
Length-to-width ratio is the length divided by the width. It is on every report, and it is the single most important number on an oval because it determines whether the stone reads classic, slender or squat.
- 1.30–1.35 — rounded, almost soft. Looks larger across but shorter on the finger.
- 1.35–1.50 — the classic band. Most people asked to pick blind choose something in here, usually near 1.40.
- 1.50–1.60 — elongated and elegant, more dramatic, particularly flattering on longer fingers.
- Above 1.60 — distinctly narrow. Not wrong, but buy it because you want it, not by accident.
There is no correct answer, but there is a wrong process: choosing an oval on weight and price alone and discovering the ratio afterwards. Decide the ratio first, then filter.
The bow-tie: the thing to actually look at
Every oval has a bow-tie — a darker band across the middle, where the pavilion geometry stops light returning to the eye. It is inherent to the shape, and a faint one is invisible in normal wear.
A heavy bow-tie is a cutting fault. It reads as a black stripe across the widest part of the stone, it does not go away in different light, and it is the single most common reason people are disappointed by an oval bought from a specification sheet.
No certificate mentions it. You have to look. That is why every oval on our site has high resolution photography and, where available, a 360° view — those exist for this exact problem. Turn the stone, and if the dark band stays dark and wide from every angle, move on to the next one.
Proportions worth checking
Beyond the ratio, a total depth in the low 60s and a table in the mid-50s to low-60s keeps most ovals bright. Very shallow ovals look big for their weight but go glassy; very deep ones look small and dark. Excellent or Very Good polish and symmetry are worth insisting on, since they are the only cut-quality grades the report gives you.
Where you can save
The oval is a brilliant cut, so it hides colour and inclusions well — though not quite as well as a round, and elongated shapes tend to hold a little colour at the pointed ends.
- Colour: G or H in white metal, I or J in yellow or rose gold, checking the tips rather than the centre. More here.
- Clarity: SI1 is realistic, with the inclusion away from the centre of the table. More here.
- Carat: just under the landmark weights, as always — and it matters less here, because the oval already looks larger than its weight.
Settings that suit it
A solitaire with an east-west or north-south orientation shows the shape most honestly. A hidden halo works unusually well on ovals — it lifts the stone and adds brightness under the girdle without changing the outline. Pavé bands echo the elongation along the finger. Whatever you choose, ask for prongs at the tips: the ends of an oval are its most vulnerable points.
