Princess Cut Diamond Jewelry

Princess cut diamonds are square or rectangular brilliant cut diamonds with sharp 90-degree corners and a modified facet pattern that produces strong light return. Developed in the 1960s–70s, the princess cut became the second most popular diamond cut globally in the 1990s and 2000s, driven by its combination of geometric modern precision and high brilliance in a non-round format. The cut's distinctive feature is the X-pattern visible through the table from above, created by the pavilion facets reflecting against each other.

Princess diamonds produce strong white light brilliance comparable to round brilliants. The cut was specifically engineered to maximize light return in a square format, and the result is a stone that reads as very bright and sparkly. Princess diamonds produce somewhat more fire (colored light) than round but somewhat less overall brilliance. In practice, most buyers looking at both shapes side by side find princess diamonds nearly equivalent to round in visual quality.

The four sharp 90-degree corners of a princess diamond are the most vulnerable points and can chip under direct hard impact. V-prong settings that cradle each corner with metal significantly reduce this risk for daily wear. Without corner protection, a princess diamond in an active wearer's ring faces a meaningful risk of corner chipping over time. Annual prong inspection is particularly important to ensure V-prongs remain secure. For buyers who want a square brilliant with less corner vulnerability, a radiant cut with cropped corners is the alternative.

Princess cuts retain color slightly more readily than round brilliants. A color grade of G or H is the sweet spot for princess diamonds in white gold settings — bright enough to read as white-faced but at a more accessible price than D–F. In yellow or rose gold settings, I or J color can work well and appear intentionally warm rather than noticeably tinted. The four corners of a princess cut can sometimes concentrate color slightly, making corner warmth slightly more visible than in a round.

Princess cut diamonds are typically 10 to 25 percent more affordable per carat than round brilliants at comparable quality. Princess cuts use diamond rough more efficiently than round brilliants, which require cutting away more material. The lower price per carat combined with strong visual quality makes princess an appealing alternative to round for buyers who want maximum stone size per budget in a brilliant-cut diamond.

V-prong settings that protect all four corners are the most important setting consideration for princess diamonds. Four V-prongs at the corners are standard for solitaire princess rings. Channel settings on the shoulders work well for princess side stones. A square halo of smaller diamonds around a princess center creates an elaborate square-within-square configuration. Cathedral shanks elevate the stone for a traditional formal appearance.

Princess cut rings at Oath include solitaire V-prong settings, halo engagement rings with a princess center, and three-stone configurations. White gold is the most popular setting metal.
