The diamond face shape is defined by cheekbone prominence (R3): the cheekbones are significantly wider than both the forehead and the jaw, typically by more than 20 percent. This creates a face with a narrow forehead, a striking mid-face, and a tapering chin. It is the rarest of the eight classifications, appearing in fewer than 5 percent of measured populations.
- Cheekbones are the single widest point. Both forehead and jaw are narrower.
- Primary identifying ratio: R3 above 1.20 (cheekbones more than 20% wider than forehead and jaw)
Best hairstyles for diamond faces
Add width at the forehead and at the chin while letting the cheekbones remain the natural focal point.
For women
- Styles with volume or fringe at the forehead level (curtain bangs, side-swept fringe)
- Chin-length bobs that add visual width at the chin
- Textured mid-length waves
- Side parts that add asymmetric width at the temples
- Sleek center-part pulled back styles that expose the narrow forehead and amplify the cheekbone-to-forehead contrast
- Very short cuts that emphasize cheekbone dominance without softening
For men
- Side-swept fringe that adds forehead width
- Medium textured styles with temple volume
- Balanced fades that do not expose the narrow forehead
- Very tight fades with no volume on top
Why these work: R3 above 1.20 means cheekbones are the dominant width. The styling goal is to bring forehead and chin widths visually closer to cheekbone width, creating balance.
Best glasses for diamond faces
Frames with width across the top add visual width at the forehead level, balancing cheekbone dominance.
- Cat-eye frames that are wider at the top
- Browline frames
- Frames that sit high on the face
- Round frames that sit in the middle of the cheekbone zone and amplify them
- Narrow frames that emphasize facial narrowness
Complete styling guide for diamond face
Necklines and clothing
High necklines and turtlenecks create a visual line at the neck that frames the cheekbones without competing.
Accessories and earrings
Stud earrings and small drops are ideal because they do not add width at the jaw or cheek level.
The core principle: Your goal is to add width at forehead and chin levels to create a diamond that reads as more balanced.
