Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, casting a delicate shimmer that dances along the gentle curve of a 14K rose gold band. This solitaire ring balances bold geometry with soft warmth, its low-profile setting crafted to sit comfortably for everyday wear.

Each ring is meticulously shaped and polished in our Williamsburg studio, where the rose gold band is hand-finished to a smooth comfort fit. The marquise stone is securely set with precision prongs that showcase its tapered drama while protecting its edges, ensuring durability without sacrificing elegance.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both ethical sourcing and environmental mindfulness.

The slender band and modest height make this ring ideal for those who appreciate a refined statement piece that layers seamlessly with other bands or stands alone with quiet confidence. Its shape naturally elongates the finger, lending a graceful presence without overwhelming the hand.

Should you need resizing, our in-house artisans adjust each piece with care to maintain its integrity and finish.
