Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a slender, graceful shadow that seems to stretch beyond the hand. This three-stone semi-set engagement ring in 10K yellow gold frames a 9 x 4.5 mm marquise center, its shape evoking a quiet drama that feels both intimate and expansive.

Each element is carefully crafted in our Williamsburg studio, where the warm glow of yellow gold is hand-finished to a soft polish that complements the diamond’s sharp geometry. The three-stone setting balances presence with wearability, designed with a low profile that slips comfortably beneath gloves or daily wear. The band’s gentle curve and subtle taper ensure a natural fit, while the semi-set design invites you to select a center stone that resonates with your personal story.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both the earth and your values. This ring’s ethical foundation is as deliberate as its design, reflecting a commitment to sustainability without compromise.

Ideal for those who appreciate a blend of classic romance and modern refinement, this ring suits slender to medium finger shapes, its elongated marquise form visually lengthening the hand. The three-stone arrangement adds depth and meaning, perfect for stacking alongside a wedding band or worn solo as a statement of enduring connection.

Should resizing be needed, our Brooklyn studio handles adjustments with precision, ensuring your ring fits as naturally as it feels. Typical lead times accommodate thoughtful customization without rush.
