Lab-Grown Diamond Engagement Ring

Light catches the marquise’s elongated silhouette, casting a slender beam that seems to stretch beyond the hand. This semi-set solitaire invites your choice of a 10 x 5 mm lab-grown diamond, its pointed ends echoing a quiet drama balanced by the soft gleam of 18K white gold.

Crafted in Williamsburg, the band’s smooth, low-profile shank curves gently for everyday ease, designed to sit comfortably beneath gloves or alongside a wedding band. The setting’s delicate prongs hold the stone securely while allowing maximum light to animate its facets, revealing the marquise’s signature blend of elegance and edge.

Each piece reflects a commitment to ethical jewelry, featuring a lab-grown diamond that offers clarity and brilliance with a smaller environmental footprint. The ring’s refined silhouette suits hands that appreciate subtle statement and timeless romance without excess.

Should you wish to adjust the fit, resizing is handled with care by our Brooklyn studio artisans, ensuring the ring remains as comfortable as it is captivating. Lead times vary slightly depending on stone selection, but every step is transparent and collaborative.
