Best Glasses for a Diamond Face Shape

The best glasses for a diamond face are oval, round, or light cat-eye frames, because their soft curves add gentle width at the brow and jaw while easing the visual emphasis on already-prominent cheekbones. Diamond faces are narrow at both the forehead and jaw with the cheekbones as the clear widest point, so the goal is softness and balance rather than more angularity. Not sure your face is diamond? Our AI face shape detector covers the five most common shapes (oval, round, square, oblong, and heart) so confirm a diamond face with the manual method in our how-to-determine guide.

The principle: soften the cheekbones, don't sharpen them further

A diamond face is defined by a narrow forehead and narrow jaw, with cheekbones that are distinctly the widest measurement and a face that's longer than it is wide. Because the cheekbones are already the face's most striking feature, frames that add more sharp angles at the widest point can look over-emphasized. Curved frames spread visual attention more evenly across the whole face, easing the contrast between narrow forehead, wide cheekbones, and narrow jaw (Zenni Optical face-shape guide).

Diamond is one of the rarer face shapes, and its defining trait (a narrow forehead and jaw framing wide cheekbones) is often considered highly photogenic. The goal with glasses is never to hide the cheekbones, but to add just enough width at the brow and jaw so the whole face reads as proportionate rather than sharply angular at one point.

Recommended frame shapes for a diamond face

• Oval frames. A gently rounded shape that softens the cheekbone area without hiding it.
• Round frames. Add curvature that balances the face's angular high points.
• Light or thin cat-eye frames, a subtle upsweep highlights the eyes and brow without adding harsh geometry.
• Rimless or semi-rimless frames. Minimal frame detailing keeps focus on the face rather than competing with the cheekbones.
• Frames with detailing along the brow line. A touch of width at the top helps balance the narrower forehead.

Frame size, color and lens tips for a diamond face

Aim for a frame width close to your cheekbone width rather than narrower, since an undersized frame can make the cheekbones look even more prominent by contrast. Softer, warmer frame colors tend to read as more balancing than stark black, which can add extra visual sharpness to an already-angular face. A slightly curved lens shape, even within an otherwise geometric frame, keeps the overall look softer.

Frames to avoid for a diamond face

• Narrow, sharply angular frames. These can make already-prominent cheekbones look more pointed.
• Heavy geometric frames, bold hexagonal or angular shapes compete with the face's natural angularity rather than balancing it.
• Frames that stop exactly at the cheekbone's widest point. This can visually emphasize just how wide that point is; slightly wider frames balance it better.
• Frames narrower than your forehead. Undersized frames draw more attention to the width difference between forehead and cheekbones.

Sunglasses for a diamond face

Oval and round sunglasses remain the top picks, softening cheekbones the same way they do in prescription glasses. Cat-eye sunglasses with a subtle sweep also work well, adding personality without sharpening the face's existing angles (Solstice Sunglasses face-shape guide). Since sunglasses are typically sized slightly larger than prescription frames, this is a good category to size up in width if you're between two frame sizes.

For women

Oval or round frames in warm, soft tones balance the cheekbones elegantly. A light cat-eye is a good middle ground if you want more personality than a plain oval or round shape offers. Hairstyles with volume at the temples or a soft side part pair well with these frame choices, adding a touch of width near the forehead that echoes what the frames are already doing.

For men

Round wire frames or oval acetates in matte finishes look clean without overstating the cheekbones. Rimless styles are a strong, understated choice for everyday wear. Aviator sunglasses with a slightly rounded bottom are a dependable option for sun protection, and a beard with fuller width at the jaw can help balance a narrow chin in the same way the frames balance the forehead.

Diamond vs. oval face glasses: what's the difference?

Diamond and oval faces share the same widest point (the cheekbones) which is why they're sometimes confused. Oval has a gentle taper with a forehead only slightly wider than the jaw, so almost any frame shape works. Diamond has a distinctly narrower forehead and jaw framing much wider cheekbones, so frames need to actively soften that contrast rather than simply add personality. Compare your forehead and jaw width to your cheekbones, or use the manual measurement method to confirm which applies to you.

Diamond is often described as one of the least common face shapes, which makes it a particularly recognizable and photogenic structure once the right frame highlights it rather than fighting it.
