If you have a diamond face shape, the best sunglasses usually soften strong cheekbones while adding a little width at the brow or upper frame. That is why cat-eye, oval, softly rounded and balanced oversized styles tend to work so well.
This guide explains what makes a frame flattering on a diamond face, which shapes are easiest to wear, and where to start shopping at By Our Bias.
Quick Answer: What Sunglasses Suit a Diamond Face?
If you want the short version, choose sunglasses that balance prominent cheekbones and create a little softness through the upper frame.
- Best shapes: cat-eye, oval, softly rounded square, brow-detail frames and balanced oversized styles
- Best visual effect: softening the cheek area while adding width near the temples or brow line
- Best fit detail: frames that sit cleanly on the face without looking too narrow at the top
- Usually less flattering: very narrow frames or tiny angular styles that over-emphasise the cheekbones
For an easy place to begin, browse the Best Sellers and Core Collection to compare softer statement shapes against cleaner everyday pairs.
How to Tell if You Have a Diamond Face Shape
A diamond face shape usually has defined cheekbones as the widest point of the face, with a narrower forehead and a narrower chin. The overall effect is sculpted, balanced and slightly angular through the centre of the face.
If sunglasses often feel strongest through your cheeks rather than your jaw or forehead, this guide is likely the right fit.
Why Certain Sunglasses Work So Well on Diamond Faces
Diamond face shapes already have striking bone structure, so the goal is not to add more sharpness everywhere. The most flattering sunglasses either soften the lines or create a touch more width at the brow to balance the face.
The right pair can:
- highlight cheekbones without making them look too dominant
- bring visual balance to a narrower forehead and chin
- make the face feel slightly more open and lifted
- add polish without fighting your natural structure
Best Sunglasses Shapes for a Diamond Face
1. Cat-Eye Sunglasses
Cat-eye frames are one of the best choices for a diamond face because they lift the outer corners and bring attention upward. That helps balance the width at the cheekbones and creates a flattering, polished finish.
If you like a feminine frame with some definition, start here.
2. Oval and Softly Rounded Frames
Oval and softly rounded sunglasses work well because they smooth out the angles in the face. On a diamond face, they can make the whole look feel more balanced and easy.
The trick is to choose rounded styles with enough presence to feel intentional, not tiny circles that disappear against the cheek area.
3. Soft Square Sunglasses
A softly squared frame gives you structure without making the face look too sharp. This is a good middle ground if you want an everyday pair that feels cleaner than oval but gentler than a hard rectangle.
4. Brow-Detail Frames
Frames with a stronger upper line help create width at the top of the face, which is especially flattering on diamond face shapes. This can be subtle rather than dramatic. Even a cleaner top line can do the job.
5. Balanced Oversized Sunglasses
Slightly oversized frames can work beautifully on a diamond face because they spread the visual weight more evenly across the face. The key is balance. You want statement, not bulk.
Styles like Keep Your Distance are useful if you want a little more fashion presence without losing proportion.
What to Avoid if You Have a Diamond Face
There are no strict rules, but a few shapes can be harder to balance.
- Very narrow frames can make cheekbones look wider
- Tiny geometric sunglasses may over-accentuate facial angles
- Top-heavy frames that are too severe can make the face feel sharp rather than balanced
- Very small lenses often do not give enough visual width across the upper face
If you like a sharper frame, choose one with softer corners or more lens depth so it still feels balanced.
How to Choose the Right Fit
Fit matters just as much as shape. On a diamond face, the strongest sunglasses usually sit comfortably across the cheek area while giving a little more visual breadth at the top.
Look for:
- frames that do not pinch visually through the temples
- a clean fit that does not sit too high into the cheeks
- enough lens height to feel balanced against prominent cheekbones
- slight width or lift through the upper outer corners
If you want to compare styles quickly, use the Best Sellers page first, then narrow to shapes that feel softer or more lifted.

Styling Tips for Diamond Face Shapes

- Tortoiseshell, champagne and softer translucent tones can make structured frames feel easier
- Cat-eye and lifted outer corners work especially well with cleaner hair and necklines
- If you want one pair for everyday wear, choose a balanced frame rather than an ultra-trend shape
- If you want a statement look, go larger rather than narrower
