What Is Moissanite Fire and Brilliance?

Why moissanite looks lively
Moissanite has strong light dispersion, so it can show pronounced rainbow flashes under direct or spot lighting. It also returns substantial white light when well cut.
Lighting changes the effect
Soft daylight may make a stone look bright and crisp, while jewelry-store spotlights can intensify colored flashes. Videos filmed under concentrated lighting may exaggerate either effect.
Cut controls performance
Facet pattern, proportions, polish, and symmetry affect where light returns and where dark contrast appears. A larger stone is not automatically more brilliant than a well-cut smaller one.
Buyers who prefer restrained sparkle may favor step cuts or certain elongated cuts, while those seeking maximum liveliness may prefer brilliant facet patterns.
