The Science of Sparkle

Diamond sparkle is the result of how light interacts with a diamond’s facets — producing fire, brilliance, and scintillation.

• Brilliance: White light reflection (brightness).
• Fire: Dispersion into rainbow colors.
• Scintillation: The contrast of light and dark when the diamond moves.

The cut of a diamond is the single most important factor affecting its sparkle. Precision determines how well it reflects and refracts light.
Ideal Cut: Maximizes light return.
Poor Cut: Allows light to escape, creating a dull appearance.

A diamond’s facets act as tiny mirrors. The number, shape, and arrangement directly influence light performance. A Round Brilliant cut has 57-58 facets designed for maximum light return, while fancy shapes have unique patterns contributing to their specific sparkle.

What gives a diamond its soul? Light performance.
Reflection: Bouncing light off the surface.
Refraction: Bending light to add depth.
Dispersion: Splitting light into spectral colors (Fire).

Even a flawless diamond can look dull if dirty. Oils and dust block light entry. Regular cleaning with warm soapy water and a soft brush restores that breathtaking brilliance.

Myth: Bigger diamonds sparkle more.
Truth: Cut quality determines sparkle, not size. A small, well-cut diamond will outshine a large, dull one.

Myth: All diamonds sparkle the same.
Truth: Every cut and facet pattern creates a unique light signature.
