Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances along the hand. This three-stone semi-set engagement ring frames a 7 x 3.5 mm marquise center with two delicately positioned side stones, each held in a secure 18K yellow gold setting that warms the skin with subtle radiance.

Crafted in Williamsburg’s artisan workshops, the ring’s low-profile mounting balances elegance with everyday wearability. The polished band curves gently, offering a comfort fit that feels natural from morning coffee to evening strolls. Each prong is meticulously finished to cradle the stones without excess metal, allowing light to flood the facets and reveal the marquise’s signature tapered drama.

Our diamonds are lab-grown, embodying clarity and brilliance while reflecting a commitment to sustainable, ethical jewelry practices.

Designed for those who appreciate refined geometry and a statement that elongates the finger, this ring pairs beautifully with stackable bands or stands alone with quiet confidence. Its semi-set nature invites you to select a center stone that resonates personally, ensuring a truly bespoke expression.

Resizing is handled with care in-studio, preserving the integrity of the setting and comfort fit.
