"Cut"
refers to how proportionate a diamond is cut to reflect the light through the table.

Perfect cut

Light entering the diamond reflects internally from facet to facet and is reflected back through the table (top) ONLY, creating maximum brilliance.

Cut too deep

When a diamond is cut too deep, light leaks out of the bottom. Brilliance is lost and the center of the diamond will appear to be dark.

Cut too shallow

When a diamond is cut too shallow, light leaks out of the bottom. Brilliance is lost and the diamond appears watery, glassy and dark.

Three Types of "Cut"

Ideal Cut - A round "brilliant" diamond that has been cut to exact, mathematically proven proportions, best describes the Ideal Cut. Its symmetry, with 58 exactly placed facets, produces the ultimate in luster and beauty. All light entering from any direction is reflected through the top (table) and is dispersed into a display of sparkling flashes and rainbow colors.

Premium Cut - A Premium Cut diamond demonstrates subtle variations from the Ideal Cut. Although dimensional differences affect a diamond's reflection of light, a Premium Cut still achieves a harmonious balance between it's proportions and the display of brilliance.

Inferior Cut - Most diamonds are "spread" in their cutting to retain maximum weight from the original rough. A heavier diamond will result, but at a dramatic sacrifice of potential fire and brilliance.
