Princess Cut Engagement Rings

A ring whose center stone is a square brilliant: straight sides, sharp 90-degree corners, and a pyramid-shaped pavilion of chevron facets that fires light back through the square table. Developed in the late twentieth century, it became the world’s second most popular engagement shape after the round. The cut suits any gemstone — our styles and settings guide shows it across the range.

Per carat, almost always — and by a wide margin. Cutting a princess retains up to eighty percent of the rough crystal, versus roughly half for a round brilliant, and that efficiency flows straight into price. The same holds for moissanite and lab-grown diamond. The trade-off: a princess faces up slightly smaller than a round of equal weight, since more mass hides in its deep pavilion.

Uncovered, a true 90-degree corner is the most impact-prone spot in gem cutting — which is why no serious princess setting leaves one exposed. V- or L-shaped prongs cap each corner in this collection, and bezel and channel settings enclose them entirely. Protected that way, the square brilliant handles daily wear confidently, especially in hard stones like moissanite (9.25 Mohs) and sapphire (9). Each listing details its corner protection.

Brilliance-first stones shine hardest: moissanite’s fire and lab diamond’s crisp white light both thrive in chevron faceting. Color-forward choices work beautifully too — icy aquamarine, teal sapphire, genuine ruby, color-shifting alexandrite, and blush morganite — because the dense flash pattern carries color in glittering steps. Even opaque black onyx turns the square into a bold graphic statement.

Corners. The princess keeps them sharp and its sides dead straight — crisp, modern, architectural. The cushion rounds both into a pillow outline with a softer, vintage register and slightly gentler sparkle. Durability also differs: the cushion’s rounded corners need no special protection, while the princess relies on its corner prongs. Same square footprint on the finger — the choice is temperament, sharp versus soft.

The princess is the true square brilliant. The radiant stretches the idea into a rectangle with cropped, durable corners and crushed-ice fire. The emerald cut leaves the brilliant family altogether — stepped parallel facets, long mirror flashes, understated glamour. Choose princess for sharp geometry and sparkle, radiant for elongated fire, emerald for composed architecture. All three reward high-clarity stones.

Corner-capping prongs are the baseline; from there, a solitaire keeps the square austere and modern, a halo frames it in sparkle and visible size, and a hidden halo tucks the accents beneath for a clean top view. Art deco and vintage-styled settings are a natural pairing — the square brilliant’s geometry echoes deco design language almost exactly, milgrain and stepped shoulders included.

Yes — most designs are offered in three build levels: 925 sterling silver (92.5% solid silver alloy), 14K gold vermeil (a thick 2.5-micron gold layer over sterling, per FTC standard), and solid 14K gold stamped 585, made to order in yellow, rose, and white; white metals carry a bright rhodium finish. Certified lab-grown diamond versions ship with their IGI paperwork.

The square’s straight sides are the easiest in bridal to stack against — a plain straight band sits perfectly flush with no gap, channel-set bands echo the geometry stone for stone, and baguette accents repeat the straight lines in miniature. Matching sets from women’s wedding bands or his-and-hers couples rings coordinate the pairing from the start, with complimentary engraving available on both rings.

The name is pure twentieth-century marketing — coined as cutters refined square brilliant designs through the 1960s and 70s (Basil Watermeyer’s Barion cut among the milestones) and settled into today’s form by the 1980s. The regal branding stuck because it matched the stone’s character: a modern cut with no antique pedigree that nonetheless reads as classic. It remains the youngest shape among the world’s favorites, and the sharpest.

Lukewarm water, mild dish soap, and a soft brush keep the chevron facets bright — pay a moment’s attention beneath the stone, where the deep pavilion collects film that dulls the fire. Check the four corner prongs gently now and then; they do the cut’s hardest work. Softer stones skip ultrasonic cleaners, per each listing’s notes, and our care guide covers the full routine.
