Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set solitaire ring offers a refined foundation for your chosen stone, crafted in warm 14K rose gold that balances softness with enduring strength.

The band’s low-profile setting ensures the diamond sits close to the skin, minimizing snagging while maintaining a confident presence. Expertly finished in Williamsburg, the smooth shank curves comfortably for daily wear, with precise prong placement that secures without overwhelming the stone’s distinctive shape.

Each lab-grown diamond reflects a commitment to sustainability, offering clarity and brilliance without the environmental cost of traditional mining. The rose gold’s gentle hue complements a variety of skin tones, making this solitaire a versatile choice for those who appreciate subtle elegance and ethical craftsmanship.

Designed for hands that value understated sophistication, the ring’s slim profile pairs effortlessly with other bands or stands alone with quiet assurance. Its semi-set nature invites personalization, allowing you to select a marquise diamond that resonates with your unique story.

Should resizing be needed, our Brooklyn studio provides careful adjustments to maintain the ring’s balance and comfort. Typical lead times accommodate thoughtful customization without rush.
