What is the main feature of a brilliant cut?

The main feature of a brilliant cut is characterized by the presence of numerous triangular or kite-shaped facets. This specific facet arrangement is designed to maximize the reflection and refraction of light within the stone, resulting in exceptional brilliance and sparkle. The geometry of these facets allows them to effectively capture and disperse light, creating a striking visual effect that sets brilliant-cut stones apart from other cut styles.

In contrast, while a smooth and domed appearance may pertain to certain styles of cuts, it is not specific to the brilliant cut. The bumpy, grape-like growth refers to a characteristic often seen in raw gemstones or in certain organic materials, which does not apply to the precise geometry of faceted stones. A thin layered structure is more commonly associated with certain types of minerals or formations rather than the intricacies of gemstone cutting. Therefore, the distinguishing feature of triangular or kite-shaped facets in the brilliant cut clearly highlights its design for optimal light interaction.
