Glasses for diamond face shape: how to choose, and 8 frames that work
Wide cheekbones, narrow forehead and chin: a diamond face shape calls for a strong top line and frames at least as wide as the cheekbones. Cat-eyes, ovals with a bold top rim, rimless. The rules and eight frames selected by OCCHIO!.

A diamond face shape wants a line on top.
Wide, high cheekbones, narrow forehead, narrow chin: this is the least common face shape and the most sculpted. The widest point is mid-face, and that is exactly where the glasses sit. The task is to visually widen the forehead and accompany the cheekbones without cutting across them. Below, the rule translated into shape, width and colour, with eight models from the OCCHIO! selection that apply it.
where to put the visual weight: a marked top rim that widens the forehead
the minimum frame width: never narrower than the widest point of the face

Three rules, in order
1. A strong top line. It is the opposite of the heart shaped face. A thicker, darker top rim, or one with upswept outer corners, adds width to the forehead and brings the face back into balance.
2. At least as wide as the cheekbones. A frame narrower than the cheekbones makes them stand out even more. Better a frame that reaches the widest point of the face or goes slightly beyond it.
3. Soft below. The chin is narrow: the lower part of the frame should be light or curved. Ovals and cat-eyes with a rounded lower rim work better than narrow rectangles.
Which shape to choose
The cat-eye is the natural shape for a diamond face: it widens the upper part and lifts the gaze towards the temples. Ovals with a bold top rim do the same more discreetly. Rimless frames work too, because they draw no line across the cheekbones. For men, the cat-eye becomes an oval that is squared off at the top, or a browline shape with an acetate upper part.
What to avoid
Narrow, small frames that leave the cheekbones exposed. Shallow rectangles with a heavy lower rim. Shapes that widen at the bottom, such as aviators with a very wide teardrop: they shift volume towards the chin, which on a diamond face is already the narrowest part.

If the widest part is the forehead and the chin is narrow, the face is heart shaped and the opposite applies: glasses for heart shaped face. If the features are soft and regular: glasses for oval face. The other guides: round face, square face, long face, and the face shape guide. To browse the selection: cat-eye optical, cat-eye sunglasses, ovals.
What glasses suit a diamond face shape?
Frames with a strong top line and at least as wide as the cheekbones: cat-eyes, ovals with a bold top rim, rimless frames. They widen the forehead and accompany the cheekbones without cutting across them.
Which sunglasses for a diamond face shape?
Cat-eyes and ovals with a marked upper part, wide enough to cover the cheekbones. Best to avoid aviators with a very wide teardrop at the bottom, which shift volume towards the narrow chin.
Glasses for a diamond face, men: what to choose?
Ovals and browline shapes with an acetate upper part, or rimless frames in titanium. They give the same upper line as the cat-eye in a more understated version.
Which colour to choose?
A bold or dark colour on the upper part of the frame: black, tortoise, dark green. It can lighten towards the bottom. Thin metals work if the shape rises towards the temples.
How do I know if I have a diamond face shape?
The cheekbones are the widest point, high and pronounced; forehead and chin are both narrow. If the forehead is the widest part, the face is heart shaped; if cheekbones, forehead and jaw have similar widths, it is oval.
