Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, casting a delicate shadow that dances with every movement. This 12 x 6 mm center stone, embraced by a halo of finely set pavé diamonds, creates a luminous frame that amplifies its graceful silhouette.

Crafted in 14K white gold, the ring’s low-profile halo setting balances sparkle with everyday wearability, while the smooth comfort-fit band ensures it rests gently against the finger. Each facet is polished and inspected in our Williamsburg studio, where precision meets quiet artistry.

Our lab-grown marquise diamond offers a clarity and brilliance that honors both beauty and conscience, reflecting a commitment to sustainable, ethical jewelry without compromise.

Designed for those who appreciate a refined statement, this ring complements slender to medium finger shapes, its tapered form elongating the hand with subtle drama. The halo setting also pairs effortlessly with stacking bands or a wedding band, thanks to its thoughtful proportions.

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