You probably think you have an oval face. Most people do. It’s the default setting in our brains when we look in the mirror and try to categorize the skin and bone staring back at us. But then you try on a pair of cat-eye glasses or attempt that "clean girl" slicked-back bun, and suddenly, something feels... off. Your cheekbones look massive. Your forehead seems tiny. Your chin is sharp enough to cut glass.
That’s the diamond shape of face reality.
It is arguably the most coveted structure in high fashion—think peak-era Linda Evangelista or Cillian Murphy—but it’s a total headache to style if you’re following generic beauty advice. People mix it up with heart shapes or ovals constantly. They aren't the same. Not even close. A heart shape has a wide, expansive forehead. An oval is balanced and curved. A diamond? It’s all about the drama of the zygomatic arches—those cheekbones—paired with a narrow hairline and a narrow jaw. It’s angular. It’s rare. And honestly, it’s a bit of a genetic jackpot if you know how to handle the proportions.
What actually defines the diamond shape of face?
Stop looking at those oversimplified 2D charts for a second. To know if you actually have this, you need to feel your bone structure. The defining trait of a diamond shape of face is that the widest part of your entire head is at your temples or slightly below, right on the cheekbones.
If you take a measuring tape, you’ll find that the distance across your cheeks is significantly greater than the width of your forehead. Then, look at your jawline. In a diamond profile, the jaw doesn't square off. It tapers down into a pointed or very narrow chin.
It’s a game of triangles. You’ve basically got two triangles meeting base-to-base at your eyes. Because the forehead is narrow, it can make the face look "pinched" at the top if you wear your hair too flat. Dr. Stephen Marquardt, who famously studied facial symmetry through his "Golden Mask" theory, noted that while the "ideal" is often cited as oval, the diamond's high-set cheekbones are what create the most striking photographic shadows. It’s why models love it. The camera finds the planes of a diamond face effortlessly.
The big mistake: Diamond vs. Heart vs. Triangle
I see this all the time on TikTok and Pinterest. Someone with a slightly pointy chin claims they have a diamond face.

Wait. Look at the forehead.
If your forehead is the widest part of your face and it tapers down to a point, you have a heart-shaped face. Think Reese Witherspoon. If your jaw is the widest part and your forehead is narrow, that’s a pear or triangle shape. The diamond shape of face is a literal outlier because it is narrow at both the top and the bottom.
This matters for one reason: volume. If you have a heart shape, you want to hide the forehead. If you have a diamond shape, you actually want to show the forehead or add width to it to balance out those killer cheekbones. If you hide a diamond's forehead with heavy, straight-across bangs, you end up looking like a wedge. It swallows your features. You lose the symmetry that makes the shape so distinct in the first place.
How to style the angles without looking "sharp"
Let’s talk hair.
The goal with a diamond shape of face is never to hide the cheekbones—why would you hide your best asset?—but to soften the "pointiness" of the overall silhouette.
- The Chin-Length Bob: This is the gold standard. By having the hair hit right at the jawline, you add visual weight to the narrowest part of your face. It "fills in" the gaps around your chin.
- Side-Swept Bangs: Since the forehead is narrow, heavy bangs are a risk. They can make your head look triangular. Side-swept fringe creates an illusion of width at the hairline, which balances the cheeks.
- Long Layers with a Side Part: Center parts are tough for diamonds. They bisect the face and emphasize the length and the point of the chin. A side part breaks up the angles.
If you’re a guy with this shape, you’ve hit the lottery for beard growth. A diamond-shaped face is the one profile that benefit immensely from a full, squared-off beard. It adds the "bulk" to the jawline that the bone structure lacks, effectively turning a diamond into a more "traditionally masculine" square or oval shape.

Glasses and Accessories: Avoiding the "Bug-Eye" Look
Buying sunglasses for a diamond shape of face is a nightmare if you don't know the rule of opposites. Because your cheekbones are already wide, you want to avoid frames that are wider than your face. If the temples of the glasses stick out past your cheekbones, you’re going to look like an insect.
Top-heavy frames are your best friend. Clubmasters, semi-rimless styles, or even upward-curving cat-eyes. They draw the eye upward and outward, mimicking the width you need at the temple area to match your cheeks. Stay away from tiny, narrow frames. They get lost on your face and make your cheekbones look disproportionately massive.
When it comes to earrings, think width, not length. Long, thin dangles just emphasize the length of a diamond face. Chandelier earrings or hoops that sit wide are better. They create a horizontal line that counters the verticality of your bone structure.
Why celebrities crave this specific bone structure
We see this shape everywhere in Hollywood, even if we don't realize it. Jennifer Lopez is the poster child for the diamond shape of face. Notice how her stylists almost always give her volume at the top or very wide, voluminous waves? That’s to prevent her face from looking too narrow.
Megan Fox is another one. Look at her cheekbones compared to her jaw. The taper is incredible. This shape ages exceptionally well because the high cheekbones provide a natural "shelf" for the skin, preventing the sagging that often happens with rounder or more "fleshy" face shapes. You essentially have a built-in facelift.
Real-world contouring for diamonds
Forget the generic "3" shape contouring you see in beauty tutorials. It doesn't work for you.

If you have a diamond shape of face, your contour needs to be surgical. You already have shadows under your cheekbones. If you add deep contour there, you risk looking gaunt or "hollowed out." Instead, focus on highlighting.
- Highlight the forehead: Use a concealer a shade lighter in the center of the forehead and spread it slightly toward the temples. This creates the illusion of more width.
- Highlight the jawline: Apply highlighter along the edges of your jaw to make it appear broader.
- Minimal contour: Only apply a tiny bit of contour to the very tip of the chin if you want to soften the point, and maybe a smudge on the actual "peak" of the cheekbone if you want to recede the width a bit.
The psychological impact of facial geometry
There’s some interesting (though admittedly debated) research in the field of physiognomy—the old-school study of facial features and personality. While mostly considered a pseudoscience today, modern perceptual psychology suggests we perceive different face shapes in specific ways.
Angular faces, like the diamond, are often associated with "intensity" or "authority." Because the features are sharp rather than soft and round, people with a diamond shape of face are often perceived as being more observant or sophisticated. It’s a "strong" face. It lacks the "approachability" of a round face but gains a sense of "prestige." Whether that’s true or just a byproduct of how we see movie villains vs. protagonists is up for debate, but the impact on first impressions is real.
Actionable steps for your shape
If you've just realized you're a diamond, don't change everything at once. Start with the "Rule of Two."
First, check your hair part. If you’ve been rocking a middle part and feeling like your face looks too long, flip it to the side. See how that instantly changes the width of your forehead?
Second, look at your eyebrows. For a diamond shape of face, a curved or slightly rounded brow is better than a sharp, angular one. You already have enough angles. You don't need your eyebrows to be daggers, too. Softening the arch helps to counteract the sharp point of the chin.
Go to a mirror. Pull your hair back completely. Trace the outline of your face on the glass with a piece of old soap or a lip liner. If the widest points are your ears/cheeks and everything else pulls inward like a kite, you're a diamond. Own it. It’s the rarest shape for a reason.
Stop trying to soften every edge. Sometimes the best look for a diamond is to lean into the drama. Slick that hair back, let the cheekbones do the talking, and wear the boldest frames you can find. You have the structure most people try to fake with filler and makeup. Use it.
