Lab-Grown Diamond Engagement Ring

When light catches the elongated points of a marquise diamond, it creates a striking silhouette that both sharpens and softens the hand’s natural lines. This semi-set solitaire ring in 10K rose gold offers a delicate balance between bold geometry and subtle warmth.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort without sacrificing security. The rose gold’s gentle blush complements the marquise’s crisp facets, while the smooth finish ensures a seamless fit beneath gloves or alongside stackable bands. Each piece is meticulously inspected in our Williamsburg studio to meet exacting standards of polish and durability.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Designed for those who appreciate refined craftsmanship and modern wearability, this ring suits slender to medium finger sizes and pairs effortlessly with other fine jewelry. Its streamlined silhouette minimizes snagging, making it ideal for daily life.

Should you need a custom fit, resizing is available to ensure the ring feels as natural as it looks.
