Lab-Grown Diamond Engagement Ring

Light catches the marquise’s tapered points, casting a subtle sparkle that draws the eye along its elongated silhouette. This solitaire semi-set invites you to select a 6 x 3.5 mm lab-grown diamond, poised to sit low and secure within a 14K rose gold band, finished with a smooth comfort fit that feels natural for everyday wear.

Crafted in Williamsburg, Brooklyn, the mounting features a refined prong setting designed to protect the stone’s delicate tips while maintaining a sleek profile that slips easily beneath gloves or sleeves. The rose gold’s warm glow complements the diamond’s brilliance, offering a modern yet understated foundation for your chosen gem.

Each lab-grown diamond reflects a commitment to ethical sourcing and sustainability, ensuring clarity and beauty without compromise. This ring’s design suits those who appreciate a balance of elegance and practicality—ideal for slender fingers or as a stackable piece alongside wedding bands.

Should you need resizing or prefer a different diamond cut, our studio offers personalized consultations to tailor the ring to your lifestyle and preferences. Typical lead times accommodate careful hand-finishing and quality inspection.
