Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This three-stone semi-set ring features an 18K yellow gold band, hand-shaped and polished in our Williamsburg studio to a smooth, comfortable fit that rests lightly against the finger.

The setting’s artisan craftsmanship reveals itself in the delicate prongs designed to cradle your chosen center stone securely while allowing maximum light to pass through, enhancing the marquise’s signature brilliance and subtle fire. The low-profile mounting ensures everyday wearability without sacrificing elegance.

Each diamond is lab-grown with clarity and sustainability in mind, reflecting a commitment to ethical jewelry that honors both beauty and responsibility.

Ideal for those who appreciate sculptural form and refined detail, this ring complements slender fingers and pairs effortlessly with stacking bands or a wedding band. Its balanced proportions make it glove-friendly and suitable for daily life.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a perfect fit without compromising the ring’s integrity.
