Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set three-stone ring invites you to select a 7 x 3.5 mm marquise center, framed by two delicate side stones that enhance its tapered drama.

Crafted from warm 14K yellow gold, the band’s smooth finish and subtle taper provide a comfortable fit that feels natural for daily wear. The low-profile setting keeps the stones close to the finger, balancing presence with practicality. Each element is shaped and polished in our Williamsburg studio, where artisan hands inspect every curve and prong to ensure lasting durability and refined detail.

Our lab-grown diamonds offer the same brilliance and clarity as mined stones, with a lighter environmental footprint and transparent origins.

This ring suits those who appreciate architectural elegance with a vintage whisper—its slender silhouette elongates the finger while the three-stone design adds meaningful dimension. The comfort fit and modest height make it ideal for stacking or wearing solo, and its shape pairs beautifully with tapered or straight wedding bands.

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