Glasses for Diamond Face Shapes
The best glasses for diamond face shapes have a strong top line or a soft, curved outline. Browline, cat-eye, oval and rimless frames add width at the narrow forehead and soften the wide cheekbones. Choose a frame at least as wide as your cheekbones.
A diamond face is widest at the cheekbones with a narrow forehead and narrow chin. Check with the free face shape detector or the diamond face shape guide.
Why a strong top line helps
Glasses sit right at the widest part of a diamond face: the cheekbones. A frame with weight at the top, such as a browline, extends the brow line and makes the narrow forehead look wider. Curved lenses soften the angle where the cheekbones meet the temples. Heavy bottom rims, by contrast, add width near the cheekbones and chin area, which is less balancing for this shape.
This is the opposite of the advice for a heart shaped face, where the forehead is already wide.
Best diamond face shape glasses
| Frame | Effect | Notes |
|---|---|---|
| Browline / clubmaster | Widens the forehead | Best overall for men |
| Cat-eye | Upswept top widens at the brow | Best overall for women |
| Oval | Softens the cheekbones | Gentle everyday choice |
| Rimless | Lets cheekbones shine without adding width | Minimal look |
| Soft rectangle | Structure with rounded corners | Office classic |
| Round with a strong brow bar | Curves plus top weight | Vintage |
| Butterfly | Wide at the top, tapering down | Fashion frame |
Glasses for diamond face men
Browline frames are the standout for men with a diamond face. The thick top bar adds width where the forehead is narrow, and the thin lower rim keeps the cheekbones clear. A soft rectangle in dark acetate also works for daily wear.
Glasses for diamond face women
Cat-eye frames match the diamond face particularly well, because the wing lifts and widens the brow line. Oval and butterfly frames are softer alternatives. Rimless frames suit a minimal look and highlight the cheekbones.
Fit
- Width: at least the width of the cheekbones; a frame narrower than the cheekbones exaggerates them.
- Top line: close to or along the brows.
- Depth: medium. Very deep lenses reach down toward the cheekbones.
- Bridge: standard; a keyhole bridge adds a curved detail that softens.
Frames to approach with care
- Narrow frames, which make the cheekbones look wider.
- Small, boxy frames with sharp corners that repeat the diamond's angles.
- Bottom-heavy frames, which add weight in the wrong place.
Colour and material
Dark or patterned tops with clear or light bottoms are ideal: they put colour exactly where you want width. Tortoiseshell browlines and two-tone cat-eyes are easy to find.
Sunglasses for diamond face shapes
Cat-eye, browline, oval and rimless sunglasses all work. Oversized round sunglasses are fine if they are wide enough. Classic teardrop aviators are heaviest at the bottom; a flat-top aviator is a better option.
Glasses and hair together
A side-swept fringe and a browline frame both widen the forehead, so you do not need both at full strength. If you wear a full fringe, a lighter oval frame keeps the forehead from looking crowded. See hairstyles for diamond face.
Reading glasses and progressives
Diamond faces often have a narrow chin, so a very deep progressive frame can look heavy at the bottom. An oval or soft rectangle with medium depth and a slightly stronger top gives enough reading area while keeping the balance this guide describes.
Three frames to try first
Bring three shapes to a fitting: a tortoiseshell browline, a soft cat-eye or butterfly, and a thin metal oval. Photograph each straight on. The frame where your brow line looks widest and your cheekbones look framed rather than squeezed is your best match among glasses for diamond face shapes.
Diamond or heart?
If your forehead is the widest point, the heart shaped face glasses guide applies instead. The advice is close to opposite, so it is worth checking.
Glasses for diamond face shapes by face size
A small diamond face with fine features can be overwhelmed by a thick browline; choose a thin metal browline or a light cat-eye instead. A larger diamond face with strong cheekbones carries bold acetate well. In both cases, keep the frame wider than the cheekbones and the visual weight at the top, so the narrow forehead looks fuller.
A guide, not a rule
Cheekbones are a diamond face's signature. Pick frames that make you look like yourself, and judge from a straight-on photo.
