Sunglasses for Diamond Face Shape – A Simple Guide
Lets discuss about Best Sunglasses for Diamond Face Shape for men. Picking sunglasses isn’t always easy. You see a pair in a shop, think they look great on the stand… but the moment you try them on, something feels off.
It’s not just about the colour, how dark the lenses are, or whether they’re trending right now. The shape of your face plays a big role in how frames look on you.
If you’ve got a diamond-shaped face, you’re already starting with something quite unique. Not many people have this shape, and while that means you stand out, it also means some frames will look amazing and others… well, they’ll just look a bit “meh.”
Don’t worry — this isn’t rocket science. A few simple tips can save you from spending money on shades that end up sitting in your drawer because you never quite love them.

How to Tell if You’ve Got a Diamond Face Shape
First, let’s make sure you actually have a diamond-shaped face. This shape isn’t super common, so if you’ve always had a hard time figuring out what category you fall into, you might just be in this group.
Diamond face shapes usually have:
Cheekbones that are the widest part of the face.
A forehead that is a bit narrow.
A chin that comes in slightly at the bottom.
One quick way to check: pull your hair back completely so you can see your whole face. Stand in front of the mirror and trace the outline of your face with your finger (or lipstick if you’re feeling dramatic).
If the middle is the widest part and the top and bottom taper in, almost like the outline of a diamond stone, you’ve got your answer.
A lot of people with diamond faces also have slightly sharper cheekbones — this is what makes the right pair of sunglasses so important. The wrong style can make them look too strong, while the right style softens and balances everything.

What Your Sunglasses Should Do for a Diamond Face Shape
For this face shape, your goal isn’t to hide anything — it’s to balance it.
You want sunglasses for Diamond Face Shape that:
Add a little width to the top part of your face so it matches your cheekbones.
Bring attention to your eyes instead of just your cheekbones or jawline.
Soften sharp angles so your features look more harmonious.
Think of sunglasses like a good haircut — the best ones make your natural shape look its best without drawing attention to the “edges” you don’t want to highlight.

Sunglasses Styles That Usually Work Best
There are a few frame shapes that almost always flatter a diamond face. I’ll go through them one by one.
1. Oval Sunglasses
If you’re not sure where to start, start here. Oval sunglasses are the “safe jeans” of eyewear — they work with almost anything.
Why they work:
The rounded edges soften the sharpness of your cheekbones.
They help balance out the width of your face without looking bulky.
Extra tip: Pick a frame that’s just a little wider than your cheekbones. If it’s too small, your cheekbones will overpower it. If it’s too big, it might feel like the sunglasses are wearing you instead of the other way around.
---
2. Cat-Eye Sunglasses
If you want to draw attention to your eyes (and look a little glamorous while you’re at it), cat-eyes are perfect. The frames lift at the outer corners, which is flattering for almost any face — but especially diamond shapes.
Why they work:
They add width to the top of your face, making your forehead appear a bit broader.
They naturally “lift” your eyes, which feels fresh and flattering.
Extra tip: For everyday wear, go for a softer, rounder cat-eye. If you’re feeling bold or dressing up, the sharper styles make a statement.
---
3. Browline Sunglasses
Browline (also called clubmaster) sunglasses have a thick top frame and a thinner or rimless bottom. They’re a nice mix of retro and modern.
Why they work:
The thicker top draws the eye upward, making the forehead look a touch wider.
They balance the proportions between the top and bottom of the face.
Extra tip: A slightly curved top frame will feel more natural. Straight, flat browlines can make the forehead look too flat.
---
4. Rimless Sunglasses
Sometimes you just want something light and barely there. Rimless sunglasses have minimal framing, which lets your features stand out without adding any extra harsh lines.
Why they work:
They soften the face and keep things open.
They don’t add angles where you don’t need them.
Extra tip: Try warm lens colours like light brown, champagne, or rose to make them even softer and friendlier-looking.
---
5. Round Sunglasses
Round frames bring curves where your face has angles. They can be vintage, quirky, or classic depending on the size and colour.
Why they work:
They balance out sharp cheekbones.
They create a softer, more relaxed look.
Extra tip: Skip the tiny, John Lennon-style circles unless that’s your signature style. Medium to large works best for proportion.
---
Sunglasses Styles That Don’t Usually Work for Diamond Face Shape
Every rule has exceptions, but generally speaking:
Long, narrow rectangles make your face look even longer and sharper.
Frames wider at the bottom pull the eye downward and make the chin look pointier.
Small frames get lost against high cheekbones and look undersized.
---
Getting the Fit Right
Even if you pick the perfect style, a bad fit can ruin the look.
Width: Frames should be slightly wider than your cheekbones — just enough to balance without feeling oversized.
Bridge: The bridge (the part that rests on your nose) changes the look of your eyes. A higher bridge opens up your eyes and lengthens the nose slightly. A lower bridge brings the eyes closer together.
Lens size: Medium to large lenses are usually the sweet spot for diamond faces. That said, comfort always wins over “rules.”

Colours and Materials
Frames aren’t just about shape — material and colour change the vibe completely.
Good frame materials:
Acetate – sturdy, lightweight, and comes in a ton of colours.
Metal – thin, minimal, and works great for browline or rimless designs.
Mix of both – modern without being over the top.
Colours that usually work well:
Neutrals – black, brown, or tortoise are safe for everyday wear.
Warm tones – amber, gold, or rose soften features.
Cool tones – grey, navy, or silver give a clean, understated look.

Picking Sunglasses for Diamond Face Shape for Different Occasions
Everyday wear: Oval or browline in neutral colours — goes with everything.
Beach or outdoor sports: Lightweight frames, polarized lenses for glare, maybe a fun cat-eye or round shape for personality.
Making a statement: Oversized cat-eyes, gradient lenses, or bold patterns. Diamond faces can handle a bit of drama.

Don’t Forget Your Hair
Hair can totally change how sunglasses look on you.
Hair pulled back: Cheekbones are more visible, so softer frames help balance.
Loose waves or curls: You can go bolder with the frame shape since the hair softens the overall look.
Side-swept bangs: Look great with oval or cat-eye frames because they draw attention to your eyes.

Looking After Your Sunglasses
If you’ve found your perfect pair, take care of them:
Keep them in a case to avoid scratches.
Clean lenses with a soft microfiber cloth (never your shirt — it scratches).
Avoid leaving them in a hot car; heat can warp frames and damage coatings.
