What Are Diamond Shapes?

A Diamond shape is the diamond’s physical, geometric form. It’s usually the most distinguishable feature of a diamond, considered its personality and a symbol of self-expression.

Diamond shapes are split into two categories: round diamonds and fancy-shaped diamonds. The diamond shape is one of the most important things to consider when choosing a diamond, as it will greatly determine the appearance, meaning, and value of a diamond.

What Is The Difference Between A Diamond Shape And A Diamond Cut?

Diamond shape and diamond cut are often confused as they both play an important role in the appearance of a diamond. However, they are two different things.

Diamond shape refers to a diamond's exterior form, noticeable even from a distance. The diamond cut refers to a diamond’s facets and is best seen up close. Different diamond cuts will determine how the diamond reflects light, i.e. how brilliant a diamond is.
