Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated points of this marquise shape, it casts a subtle, graceful shadow that feels both bold and intimate. The 9 x 4.5 mm center stone is designed to draw the eye along its tapered silhouette, offering a distinctive elegance that elongates the finger.

Crafted in warm 14K rose gold, this semi-set solitaire ring provides a refined foundation ready to showcase your chosen lab-grown diamond. The low-profile setting ensures the stone sits close to the hand, balancing presence with everyday comfort. Each band is meticulously finished by hand in our Williamsburg studio, polished to a smooth comfort fit that slips on effortlessly and wears well beneath gloves or stacked with other bands.

Our commitment to ethical jewelry is reflected in the clarity and sustainability of the lab-grown diamond you select, offering brilliance without compromise. This solitaire’s streamlined design suits those who appreciate modern geometry paired with practical wearability, ideal for daily life and layering.

Should you need resizing, our Brooklyn studio handles adjustments with care to maintain the ring’s integrity and finish. Typical lead times allow for personalized attention to detail, ensuring your ring is as unique as your story.
