Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a marquise diamond catching morning light, its elongated silhouette casting a delicate shadow along your finger. This semi-set engagement ring invites you to choose a 6 x 3 mm marquise stone, whose pointed ends and graceful shape evoke quiet elegance and subtle drama.

Crafted in warm 18K rose gold or cool 18K white gold, the mounting balances refined minimalism with secure prong settings that cradle the stone while allowing maximum light to animate its facets. The band’s slender profile ensures a comfortable fit, designed to sit low and unobtrusively for everyday wear.

Each piece is finished by hand in our Williamsburg studio, where precision meets a tactile softness in the polished surfaces and carefully inspected prongs. The ethical edge lies in the choice of lab-grown diamonds, offering clarity and brilliance with a reduced environmental footprint.

This solitaire silhouette suits those who appreciate a ring that feels intimate yet striking, ideal for slender fingers or as a standalone statement. Its low-profile setting pairs effortlessly with wedding bands or stackable rings without catching on gloves or sleeves.

Should you wish to adjust the fit, resizing is available with care to preserve the ring’s delicate balance. Lead times reflect our commitment to meticulous craftsmanship rather than rush.
