Lab-Grown Diamond Engagement Ring

Light catches the elongated marquise shape, casting a slender, dramatic silhouette that feels both bold and refined on the finger. This three-stone semi-set engagement ring in 14K white gold frames a 12 x 6 mm marquise center with two delicate side stones, emphasizing architectural clarity and modern minimalism.

Each band is hand-finished in our Williamsburg studio, polished to a soft sheen that complements the low-profile setting designed for everyday wear. The secure prong setting balances visibility with protection, while the smooth comfort fit ensures the ring settles naturally against the skin.

Crafted exclusively with lab-grown diamonds, this piece reflects a commitment to ethical jewelry—offering brilliance without compromise on sustainability. The elongated marquise shape visually lengthens the finger, making it an elegant choice for those who appreciate structured, confident design.

Its streamlined profile pairs well with stacking bands or worn solo, and the semi-set format invites you to select a center stone that resonates personally. Resizing is straightforward, handled carefully in-studio to maintain the ring’s integrity.
