This line-art diagram depicts the precise geometric layout of a round brilliant-cut diamond, highlighting the 57 or 58 facets-including 33 on the crown and 24 or 25 on the pavilion-that optimize light reflection. The symmetry and angles are engineered to maximize brilliance, fire, and scintillation, making it the most popular diamond cut worldwide. Ideal proportions follow Tolkowsky’s mathematical model for optimal light performance.
