Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every movement—its pointed ends drawing the eye along the length of the finger. This semi-set solitaire ring in 10K yellow gold offers a refined foundation for a 12 x 6 mm marquise center, designed to showcase the stone’s distinctive silhouette without distraction.

Crafted with a low-profile setting, the band sits close to the finger, balancing presence with comfort for daily wear. The warm glow of 10K yellow gold is hand-finished in Williamsburg, ensuring smooth edges and a secure fit that resists snagging. This mounting invites your choice of a lab-grown marquise diamond, inspected for clarity and cut to maximize brilliance.

Our commitment to ethical jewelry is reflected in the use of sustainable lab-grown diamonds, reducing environmental impact without compromising on sparkle or integrity.

Ideal for those who appreciate architectural elegance and a ring that integrates seamlessly with everyday life, this solitaire’s slender band complements stacking or stands confidently alone. Its low profile makes it glove-friendly and unobtrusive, perfect for active hands.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a perfect fit without altering the ring’s sleek silhouette.
