Diamond Face Shape Glasses — The Complete Buying Guide
Choosing glasses for a diamond face shape requires understanding what makes this face shape unique and which frame styles work with its distinctive proportions. Diamond faces have wide, prominent cheekbones that are the widest part of the face, combined with a narrow forehead and a narrow, pointed chin. This creates a beautiful angular silhouette that is relatively rare and highly striking.
The right glasses for a diamond face shape should minimize the width of the cheekbones, add width to the narrow forehead and chin, and soften the angular quality of the face. The wrong frames can make the cheekbones look even wider and the forehead appear even narrower.
This guide covers everything you need to know — what makes diamond faces unique, the best frame styles, styles to avoid, and tips for sunglasses and reading glasses too. Use our free Face Shape Detector to confirm you have a diamond face before buying.
What Is a Diamond Face Shape?
A diamond face shape has four defining characteristics that set it apart from other face shapes.
Wide, prominent cheekbones are the most striking feature. The cheekbones are clearly the widest part of the face, wider than both the forehead and the jaw. They often appear angular and high on the face.
A narrow forehead is the second defining characteristic. The forehead is noticeably narrower than the cheekbones. It may taper slightly at the hairline or appear relatively small compared to the prominence of the cheekbones.
A narrow, pointed jaw and chin complete the lower face. The jaw narrows significantly from the cheekbones toward a pointed or angular chin. The lower face has a delicate, narrow quality that contrasts with the wide cheekbones above.
The face length is typically longer than it is wide, giving the face an overall elongated, angular diamond outline when all four characteristics are viewed together.
Diamond faces are one of the rarer face shapes and are frequently considered striking and photogenic because of the dramatic cheekbone prominence. Many celebrated faces in fashion and film have diamond face shapes.
Famous people with diamond face shapes include Halle Berry, Jennifer Lopez, Vanessa Hudgens, and Robert Pattinson.
How to Confirm You Have a Diamond Face Shape
Before choosing glasses specifically for a diamond face, confirm your face shape with one of these methods.
Measure your face at four points: forehead width, cheekbone width, jaw width, and face length. If your cheekbone width is the largest measurement, your forehead and jaw are both narrower than your cheekbones, and your face length is significantly greater than your cheekbone width, you have a diamond face shape.
Use the mirror method: pull your hair back and look at the outline of your face. Diamond faces have a very distinctive shape — narrow at the top, widest at the cheekbones, then narrowing again toward the chin. The silhouette looks like a diamond or rhombus shape.

Diamond Face Shape vs. Oval Face Shape
The diamond face is sometimes confused with the oval face because both are longer than they are wide with a narrower chin area. The key difference is the cheekbone prominence and the forehead width.
An oval face has a forehead that is the widest part of the face, with the face gently narrowing toward the chin. A diamond face has cheekbones as the widest part, with both the forehead above and the jaw below being narrower. The dramatic cheekbone prominence in a diamond face is the clearest distinguishing feature.
If your cheekbones are clearly the widest part of your face and your forehead looks narrow compared to them, you have a diamond face. If your forehead is the widest part and the face narrows gently below, you have an oval face.
The Best Glasses for Diamond Face Shape
The goal when choosing glasses for a diamond face shape is to balance the prominent cheekbones by adding visual width to the narrow forehead and chin, while softening the overall angular quality of the face.
Oval Frames
Oval frames are one of the best choices for diamond face shapes. Their rounded, softly curved shape contrasts the angular prominence of the cheekbones and adds a gentle balance to the face. Oval frames also do not add additional width at the cheekbone level — they sit comfortably without competing with the face’s widest feature.
Medium to large oval frames work best. Very small oval frames can look too delicate against the strong cheekbones. Choose frames with some visual weight — a medium thickness frame in a warm color or a classic tortoiseshell reads well against diamond facial proportions.
Cat-Eye Frames
Cat-eye glasses are one of the most flattering styles for diamond face shapes, particularly for women. The upswept outer corners of cat-eye frames draw the eye upward and outward at the temple level, adding visual width to the narrow forehead. This directly addresses one of the main styling goals for diamond faces — balancing the narrow upper face with the wide cheekbones.
The upward sweep of cat-eye frames also creates a lifting effect that complements the high cheekbones of diamond faces beautifully. Classic cat-eye shapes in acetate frames, particularly in black, tortoiseshell, or warm colors, look particularly striking on diamond face shapes.
Rimless and Semi-Rimless Frames
Rimless and semi-rimless frames are excellent choices for diamond face shapes because they minimize visual weight at the cheekbone area. Since the cheekbones are already the most prominent feature, adding a heavy frame across that area can make them appear even wider. Rimless frames float visually across the face without adding bulk anywhere.
Semi-rimless frames with the frame across the top and open at the bottom are particularly flattering. The strong top bar adds width at the forehead level while the open bottom keeps the cheekbone area visually light.
Frames Wider Than Your Cheekbones
Choosing frames that are as wide as or slightly wider than your cheekbones is a key technique for diamond faces. When the frame width extends to or beyond the cheekbone width, it reduces the appearance of the cheekbones as the dominant widest feature. This creates more visual balance across the face.
Look for frames where the outer edge of the lens aligns with or extends slightly past the outer edge of your cheekbones when worn. This simple proportion check makes a significant difference in how balanced the glasses look on a diamond face.
Decorative and Embellished Top Bars
Frames with decorative details, embellishments, or visual interest along the top rim add visual weight to the forehead and brow area. This is beneficial for diamond faces because it draws the eye upward toward the narrow forehead, creating a more balanced visual impression.
Browline glasses — with a thicker, more prominent upper frame and a thinner or rimless lower — are a particularly good expression of this principle. The bold top draws attention to the brow and forehead level rather than to the cheekbones.
Round Frames
Round frames work well for diamond faces because their circular shape contrasts the angular quality of the face. Round glasses soften the prominent cheekbone angles and add a sense of gentleness that balances the face’s inherent sharpness.
For diamond faces, medium to large round frames work better than very small round frames. Large round frames add more width at the temple and forehead level, which is beneficial. Very small round frames can look overwhelmed by the prominent cheekbones.
Glasses to Avoid for Diamond Face Shape
Knowing which frames to avoid is equally important as knowing which ones to choose.
Narrow rectangular frames are one of the worst choices for diamond face shapes. These frames sit squarely across the cheekbone area and their narrow horizontal shape draws maximum attention to the cheekbones as the widest feature. They do nothing to add width to the narrow forehead or chin, leaving the face looking very angular and unbalanced.
Very small frames in any shape look lost against the prominent cheekbones of a diamond face. The strong facial structure needs a frame with some presence — frames that are too small or too delicate look mismatched against the boldness of diamond features.
Frames narrower than your cheekbones are problematic because they make the cheekbones appear even more prominent by contrast. Any frame that is clearly narrower than the widest point of your face will emphasize rather than balance the cheekbone width.
Angular geometric frames — sharp hexagons, aggressive rectangles with harsh corners, very square shapes — can emphasize the angular quality of diamond features rather than softening them. The exception is rounded geometric shapes like rounded squares or rounded hexagons, which add some softening curve to the geometric structure.
Very heavy, thick-rimmed frames in dark colors that sit right at the cheekbone level add bulk to the face’s already widest feature. If you love bold frames, choose ones that sit higher on the nose bridge to position the frame above the cheekbone area rather than directly across it.
Best Sunglasses for Diamond Face Shape
The same principles that apply to prescription glasses apply to sunglasses for diamond face shapes, but sunglasses offer more room for bold fashion choices.
Oversized oval or round sunglasses are ideal. Large frames add width at the forehead level and cover enough of the face to balance the prominent cheekbones. Classic large aviators work particularly well — their teardrop shape adds width at the top and tapers toward the bottom, complementing the diamond face’s proportions.
Cat-eye sunglasses are a strong fashion choice for diamond-faced women. The upswept design works well in bolder, larger sunglasses for a statement look.
Shield sunglasses and wraparound styles that are wider than the cheekbones work well and look particularly modern and striking on diamond faces.
Avoid very small round sunglasses or narrow rectangular sunglasses, which look proportionally mismatched against strong diamond features.
Reading Glasses for Diamond Face Shape
For reading glasses, the same frame selection principles apply. However, reading glasses are often chosen in a slightly more conservative style, so rimless and semi-rimless options are particularly practical — they are unobtrusive, lightweight, and do not add bulk at the cheekbone level.
For those who want more personality in their reading glasses, an oval or subtly cat-eye shaped reading frame in a warm color like tortoiseshell, amber, or burgundy looks excellent on diamond face shapes.
How Face Shape Affects Glasses Fit
Beyond the aesthetic considerations of which frames flatter a diamond face shape, practical fit considerations matter too.
Bridge fit is important for diamond faces. Because the forehead is narrow, the bridge of the glasses — the part that rests on the nose — needs to fit comfortably without the frame feeling too wide for the upper face. Choose frames with an adjustable nose bridge or a bridge width suited to a narrower forehead.
Temple length and positioning affect how glasses sit on the face. Frames where the temple attaches at or slightly above the center of the lens height tend to sit well on diamond faces, keeping the frame visually high enough to add forehead width without positioning too low at the cheekbone level.
Frame weight matters for comfort. Since diamond faces have prominent cheekbones, heavy frames that rest on or near the cheekbones can become uncomfortable over extended wear. Lightweight materials like titanium, thin acetate, or rimless styles are more comfortable for long-term wear.
Quick Reference — Best Glasses for Diamond Face Shape
The best frame styles for diamond face shapes are oval frames in medium to large sizes, cat-eye frames with upswept corners, rimless and semi-rimless frames especially with a strong top bar, round frames in medium to large sizes, and frames as wide as or slightly wider than the cheekbones.
The styles to avoid are narrow rectangular frames, frames narrower than the cheekbones, very small frames of any shape, very heavy dark frames positioned at cheekbone level, and very angular geometric frames with harsh corners.
The styling goal for all diamond face glasses choices is to add visual width to the narrow forehead, soften the angular cheekbone prominence, and create a more balanced overall impression.
