Princess

A princess cut stone is a square or rectangular cut with sharp 90-degree corners and a modified brilliant facet pattern that produces strong light return from the top of the stone. Developed in the 1960s and 1970s, it became the second most popular diamond cut after round through the 1980s and 1990s. The princess cut's defining features are its strict geometric corners and a pointed pavilion apex that concentrates light return. The sharp corners produce a characteristic X-pattern reflection visible through the table that distinguishes princess cut diamonds from all other shapes.

The princess cut's strictly geometric square outline with 90-degree corners reads as architectural and contemporary because it emphasizes pure geometric form over historical romantic associations. Unlike cushion and round cuts, which have centuries of history, the princess is a 20th-century creation designed specifically for contemporary aesthetic preferences. Its clean lines and precise angles align with mid-century modern and contemporary design sensibilities, making it the choice for buyers who want a stone that reads as clearly modern rather than vintage-inspired.

V-prong settings that cradle each of the four corners are the most recommended setting for princess cuts because they protect the vulnerable sharp corners while maintaining the square silhouette from above. Four-corner prong settings in either a square or diamond orientation also work. Channel settings suit princess-cut side stones in engagement ring shoulders. Halo settings around a princess center create either a square or softened-square frame depending on corner treatment. Bezel settings protect the corners most fully but slightly soften the geometric outline.

Princess cuts require more care for daily wear than rounded shapes because the four sharp corners are the most vulnerable points and can chip under direct hard impact. V-prong settings mitigate this risk significantly by covering each corner with metal. In a V-prong setting in 14k gold, a princess cut ring is a practical daily piece but requires more attention to avoiding impact than a round or cushion cut. Annual prong inspection is more important for princess cuts than for softer-cornered shapes.

Princess cut is primarily used for diamonds because the cut was specifically developed to maximize diamond light performance in a square format while minimizing waste of rough diamond material. The cut is also available in sapphire, spinel, and other hard colored stones where the durability of the stone at the sharp corners is sufficient. Softer stones are less commonly found in princess cuts because their corners are more vulnerable to chipping than in rounded shapes.

Princess and emerald are both rectangular-to-square shapes but are entirely different cuts. Princess uses modified brilliant faceting that produces sparkle and brilliance. Emerald uses step-cut faceting with parallel rows of rectangular facets that create an open, reflective effect with less sparkle but more visual depth and transparency. Princess reads as lively and bright. Emerald reads as elegant and transparent with a hall-of-mirrors visual character. Princess suits buyers who want sparkle; emerald suits buyers who prefer understated clarity and depth.
