The Elements Of Diamond Sparkle
-
Brilliance
The first measure of a diamond’s sparkle is brilliance, or how well it reflects white light. When you see a diamond sparkling in a dimly lit or candlelit room, what you’re seeing is its brilliance. If a diamond isn’t cut correctly, it will appear dim and dull, even in perfect lighting.
-
Fire
The second measure of a diamond's sparkle is fire, or how well it displays colored light. When you see a diamond with a rainbow-like appearance, it's a result of the correct balance of proportions from the top and bottom of the diamond. Diamonds with too deep or too shallow a cut won't refract colored light properly, resulting in a flat appearance.
-
Scintillation
The last measure of a diamond's sparkle is scintillation, or how well the diamond reflects light when it's moving, when the light source is moving, or when the person wearing the diamond is moving. When a diamond has high scintillation, it has very few spots where no sparkle occurs. In a well-cut diamond, most of the surface area of the diamond emits some visible sparkle.
