Diamond Face Shape
A face where the cheekbones are the widest measurement, noticeably wider than both the forehead and the jawline, with a narrower, more angular chin.
A diamond face shape has cheekbones that measure noticeably wider than both the forehead and the jawline, giving the face its widest point in the middle. The chin tends to be narrower and more defined. Styling advice for this shape generally focuses on adding width at the forehead and jaw to bring the proportions into visual balance with the cheekbones.

- Overall facial outline is more angular or sculptural than curved
Understanding the Diamond Face Shape
A diamond face shape is defined by cheekbones that are clearly the widest point on the face, measuring noticeably more than both the forehead and the jawline. That combination — narrow at the top, wide in the middle, narrow at the bottom — is what gives the shape its name and its more sculptural, angular appearance compared to rounder face shapes.
The general threshold used to separate diamond from other shapes is a gap of roughly 10% or more between the cheekbone width and both the forehead and jaw widths. If only one of those two gaps is present, the face is more likely heart-shaped (wide forehead, narrow jaw) or triangle-shaped (wide jaw, narrow forehead) rather than diamond.
Among the shapes covered here, diamond has some of the more consistently cross-referenced celebrity examples, which suggests it is comparatively easy to identify visually once you know to look at all three width measurements together rather than judging width from a single feature.
As with the other shapes on this page, "diamond" is a hairdressing and styling term used to describe a proportion pattern for the purposes of choosing glasses, haircuts, and necklines. It is not a medical or scientific classification.
Diamond Face Shape Examples
Both names are independently listed as diamond-shaped across three separate sources reviewed for this guide (faceshapedetector.app, glassesshop.com, and general search results), making diamond one of the more consistently cross-verified shapes in this set.
Styling Guide for Diamond Faces
These are general hairdressing and eyewear-industry conventions for complementing your proportions, not rules you have to follow.
Glasses
Frames with detailing at the top, such as browline or cat-eye styles, are commonly recommended, since they add visual width at the forehead to balance the cheekbones. Rimless or narrow frames that sit close to the cheekbone area tend to draw more attention to that already-wide point rather than balancing it.
Hairstyle
Styles with volume or texture at the forehead and chin, such as a side-swept fringe or waves that flare out near the jaw, are frequently recommended, since they add width at the narrower points of the face. Hairstyles that are slicked back and pulled tightly away from the face can leave the cheekbone width unbalanced.
Earrings
Earrings that add width near the jawline, such as chandelier or teardrop styles, are commonly suggested, since they help balance a narrower chin. Small stud earrings sit close to the cheekbone area, the face's widest point, without adding balance elsewhere.
Necklines
Necklines that draw the eye toward the shoulders and collarbone, such as a boat neck or off-the-shoulder style, are frequently recommended, since they add horizontal width lower down to balance a face that is widest at the cheekbones.
How Diamond Compares to Other Shapes
Diamond vs Heart
Both heart and diamond faces narrow at the jaw, but a heart face is widest at the forehead, while a diamond face is widest at the cheekbones, with the forehead narrower than the cheekbone measurement.

Oval and diamond faces both have their widest point at the cheekbones, but the gap between cheekbone width and forehead/jaw width is much larger for diamond faces, which gives diamond a more angular, sculptural look compared to oval's softer balance.

What makes a face diamond-shaped?
A diamond face has cheekbones that are clearly the widest measurement, noticeably wider than both the forehead and jawline. The chin is often narrow or more angular. A gap of roughly 10% or more between cheekbone width and both the forehead and jaw is the general threshold used to identify this shape.
What glasses work best for a diamond face?
Frames with detailing at the top, such as browline or cat-eye styles, are commonly recommended, since they add visual width at the forehead to balance the cheekbones. Rimless or very narrow frames tend to draw more attention to the cheekbone area, which is already the widest point.
What is the difference between a diamond face and a heart face?
Both shapes narrow toward the jaw, but the widest point differs. A diamond face is widest at the cheekbones, with both the forehead and jaw measuring narrower. A heart face is widest at the forehead specifically, not the cheekbones.
Is a diamond face shape rare?
Sources disagree. Some anthropometric-style estimates place diamond faces at around 5%, making it the least common shape by that method. Self-reported data from a large online face-shape study found the opposite: diamond was the second most common shape at close to 22% in that sample, with square appearing as the rarest instead. The conflicting rankings likely reflect differences in how each dataset was collected, so neither figure should be treated as definitive.
What hairstyles suit a diamond-shaped face?
Styles with volume or texture near the forehead and chin, such as a side-swept fringe or waves that flare at the jaw, are frequently recommended, since they add width at the narrower points of the face. Hair pulled tightly back can leave the cheekbones as the only wide point with nothing to balance them.
What if my face measures close to diamond and another shape?
Diamond is most often confused with heart, since both narrow at the jaw, and with oval, since both are widest at the cheekbones. The difference is the size of the gap: diamond has a clear gap of roughly 10% or more between cheekbone width and both the forehead and jaw, while oval's gap is smaller and heart is widest at the forehead instead of the cheekbones.
