Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a subtle, tapered sparkle that draws the eye along the finger’s natural line. This semi-set engagement ring in 18K rose gold offers a delicate balance between architectural grace and everyday ease.

Crafted with a low-profile setting, the band’s gentle curve ensures comfort beneath gloves or alongside stackable rings. The rose gold’s warm blush complements the marquise’s sharp points, while accent stones add a refined shimmer without overwhelming the design. Each piece is hand-finished in our Williamsburg studio, inspected for precision and smooth edges that wear well over time.

Choosing a lab-grown diamond means embracing clarity and sustainability without compromise, reflecting a modern approach to ethical jewelry.

Designed for those who appreciate subtle drama and practical elegance, this ring suits slender to medium finger shapes, enhancing length while maintaining a secure fit. Its streamlined silhouette works beautifully for daily wear, whether paired with a wedding band or worn solo.

Resizing is available to ensure a perfect fit, with careful adjustments made to preserve the integrity of the setting.
