Why Do Diamonds Sparkle So Much?

Diamonds captivate with their brilliance, not just shape or size, but how they interact with light. This involves understanding reflection, refraction, and dispersion.

Spark

Light reflecting off a diamond's surface is key to its sparkle. More facets mean more reflection angles; the round brilliant cut's 58 facets maximize this.

Deflect

Diamonds' high refractive index bends light significantly, creating their dazzling brilliance. Light slows and bends within the diamond, enhancing its sparkle.

Rainbow effect

Dispersion, like a prism separating light into colours, gives diamonds their "fire." Their crystal structure enhances this, creating colourful flashes. Cutters maximize dispersion for vibrant displays.

The Importance of Cut

A diamond's cut is crucial for sparkle. A well-cut diamond maximizes brilliance and fire, while a poor cut results in a dull appearance. Cut is often considered the most important factor in a diamond's quality.
