Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light that seems to stretch beyond the finger. This three-stone semi-set engagement ring in 18K rose gold frames a 12 x 6 mm marquise center with two gently tapering side stones, each facet sculpted to enhance the stone’s signature tapered drama.

Handcrafted in Williamsburg, the band’s warm rose hue complements the marquise’s vintage-inspired shape, while a low-profile setting ensures everyday comfort and ease beneath gloves or rings stacked alongside. The smooth finish and subtle curvature of the shank invite a natural fit, designed for daily wear without distraction.

Each diamond is lab-grown, offering a clarity and brilliance that honors both the environment and the wearer’s values. This ethical choice reflects a commitment to sustainable luxury without compromise.

Ideal for those drawn to romantic geometry and a statement that elongates the hand, this ring balances bold presence with refined wearability. The semi-set design allows you to select a center stone that resonates personally, making the piece uniquely yours.

Resizing is available to ensure a precise fit, crafted with care in our Brooklyn studio. Lead times vary slightly depending on stone selection, with attentive guidance offered throughout the process.
