Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it casts a subtle, tapered sparkle that draws the eye along the finger’s natural line. This solitaire semi-set features an 18K rose gold band, its warm hue complementing the stone’s graceful shape without distraction.

Crafted for everyday wear, the low-profile mounting keeps the diamond close to the hand, reducing snags while maintaining a confident presence. The band’s smooth finish and balanced weight ensure comfort throughout daily moments, from morning coffee to evening strolls.

Each lab-grown marquise diamond is selected for clarity and brilliance, reflecting a commitment to sustainable sourcing without compromise. The rose gold is responsibly sourced and hand-finished in our Williamsburg studio, where every detail is inspected before it leaves the bench.

This design suits those who appreciate architectural elegance with a modern edge—ideal for slender fingers or anyone seeking a ring that layers effortlessly with wedding bands or stackable styles. Its streamlined profile fits comfortably under gloves and rings alike.

Should you wish to adjust sizing, our in-studio experts provide precise resizing to maintain the integrity of the setting and band shape.
