The diamond shaped face is considered the rarest of face shapes. It is characterized by a narrow forehead, wide cheekbones, and a narrow chin. This distinctive shape makes it stand out, with high and prominent cheekbones often adding a dramatic touch.
While some sources mention the diamond-shaped face as the rarest, others emphasize the rarity of inverted triangle faces, particularly in females.
The inverted triangle face shape has a wide forehead, narrow jawline, and cheekbones that are less prominent than the diamond shape. It is typically characterized by a more angular structure, compared to the rounded features of the diamond-shaped face.
Ultimately, the rarity of different face shapes can vary depending on the population and ethnic background. However, based on available information, the diamond-shaped face is generally considered one of the rarer face shapes.
