Grading helps potential buyers understand a diamond's quality and characteristics, and provides a record of its unique features.

A small, rectangular step-cut diamond with four sides, often used as accent stones in rings.

A four-sided cut with two narrow angles, giving it an elongated 'diamond' shape.

GIA uses a standard system to describe a diamond's shape and cut. It combines the shape name (e.g., 'Oval') with the cutting style (e.g., 'Brilliant'), and may include additional terms like 'cut-cornered' or 'modified' for variations.

This term applies to brilliant cuts that differ from a standard brilliant cut in facet arrangement. It can also describe shape variations, like a 'Modified Pear.'

A diamond that’s not round, but has a brilliant cut facet arrangement. Even if the number of facets differs, it’s still considered a standard brilliant.

A square or rectangular modified brilliant with a trademarked name. It's popular for settings that allow for maximum sparkle due to its cut.

A square or rectangular modified brilliant with beveled corners. This cut shines brightly and retains a significant amount of the rough diamond.

Diamond shapes and cuts that differ from the standard round brilliant, including unique shapes like pear, marquise, and heart.

Similar to round brilliant grading, fancy cuts are evaluated for color, clarity, cut, and carat weight, but with specific considerations for the unique shape and cutting style of each fancy cut.

The beauty of a fancy cut is subjective and depends on personal preference, unlike the objective grading criteria for round brilliants.
