Narrow forehead and jaw, cheekbones doing all the talking.
TL;DR
Diamond face shape: A diamond face shape is widest at the cheekbones with a narrower forehead above and a narrow, tapered jaw and chin below — the outline widens to the middle and closes at both ends. It's the rarest of the standard shapes and the one where cheekbone projection dominates.
A diamond face is defined by its width pattern — where the face is widest and how it tapers. These are the tells.
Cheekbones clearly the widest point of the face
Forehead narrower than cheekbones (unlike heart)
Narrow, often pointed chin with a tapering jaw
Hollow or shadowed areas under the cheekbones are common
You can confirm your face shape in two minutes with a straight-on photo — or skip the manual measuring and let the Face Shape Detector classify it for you.
Straight-on photo: if cheekbone width beats both forehead and jaw width by a clear margin, you're diamond.
Differentiate from heart: heart's forehead rivals its cheekbones; diamond's forehead is visibly narrower.
Profile check: diamond cheekbones usually project forward too, not just sideways.
Diamond is the shape where midface measurements matter most — the cheekbones set the face's widest line, so their height and left-right evenness dominate how balanced everything reads. A slightly higher cheekbone on one side shows more on a diamond face than on any other shape, which makes it worth actually measuring rather than assuming.
Styling for face shape is about balancing the width pattern, not hiding it. The moves that consistently work:
Fringes and textured forehead coverage add width up top and frame the cheekbones instead of competing.
Avoid slicked-back styles that expose the full narrow forehead against wide cheekbones.
Beards: fuller jaw coverage adds lower-third width and squares the taper if the point feels sharp.
The free Face Shape Detector reads your width pattern from one selfie and tells you which shape you actually have — no tape measure, no guessing. The Symmetry IQ app goes further with a Face Shape view in the Symmetry Lab, rendered from your own 3D scan.
It's generally cited as the least common of the standard shapes — most faces distribute width more evenly. The combination of narrow forehead, dominant cheekbones and narrow jaw is a specific pattern.
Both are widest at the cheekbones, but oval's differences are mild and its jaw curves gently, while diamond's taper is dramatic at both ends. If your cheekbones look like the obvious headline of your face, it's diamond.
Usually — the shape is practically defined by cheekbone prominence. But 'wide' and 'high' are different measurements: a diamond face can carry its width lower on the cheekbone. Where yours sit is measurable from one photo.
