Diamond Properties

Bow-tie Effect: A bow tie is a shadowy pattern that resembles a bow tie seen from the top of the stone looking down. It is typically seen in oval, pear, or marquise-shaped diamonds.

Brilliance: The amount of white light reflected from a diamond’s surface and interior, contributing to its overall brightness.

Dispersion: The process by which white light is separated into its component colors creating a colorful display known as “fire.”

Fire: The rainbow-like effect of white light dispersing into colors when it hits the diamond’s facets.

Fluorescence: Light emitted (glowing) from a diamond when the stone is exposed to UV light; often a blue hue. It is a natural phenomenon that only occurs in around 20% of natural diamonds.

Hearts and Arrows: A visual effect seen in ideal-cut round brilliant diamonds, showing symmetrical hearts and arrows when viewed through special scopes.

Luster: The quality of light reflection from a diamond’s surface, contributing to its overall brilliance.

Scintillation: The sparkle that occurs when light reflects off a diamond’s facets.
