What does a diamond's "typical brilliance" signify?

A diamond's "typical brilliance" refers to its ability to reflect and refract light effectively, which is the essence of what creates the visual appeal and sparkle of the stone. Brilliance encompasses how well a diamond can return white light to the eye, which is influenced by factors such as its cut, proportions, and clarity. A well-cut diamond optimizes light interaction, leading to a high level of brilliance as it reflects light off its facets and disperses it, contributing to the diamond's overall aesthetic.

In contrast, other options do not directly relate to brilliance. Color intensity, carat weight, and the presence of inclusions may affect the appearance of a diamond but do not define its brilliance. Color intensity impacts hue rather than light performance, carat weight indicates size rather than light handling, and inclusions might inhibit brilliance by obstructing light paths, but they are not a measure of how well a diamond can produce brilliance overall.
