Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set engagement ring invites your choice of a 7 x 3.5 mm marquise center, framed by two delicate side stones that balance brilliance and grace.

Crafted in warm 14K rose gold, the band is shaped for comfort with a gentle curve that rests naturally against the skin. The three-stone setting is meticulously hand-finished in our Williamsburg studio, ensuring each prong secures your stones with precision while maintaining a low profile for everyday wear.

Our diamonds are lab-grown, offering clarity and sparkle with a lighter environmental footprint. This ethical approach aligns with a modern commitment to sustainability without compromising on beauty or craftsmanship.

Designed for those who appreciate refined artistry and subtle statement, this ring complements slender to medium finger shapes and layers effortlessly with stackable bands. Its low-profile setting makes it glove-friendly and suited to daily life in Brooklyn’s vibrant rhythm.

Should you need resizing or prefer a consultation on stone selection, our in-studio experts provide personalized guidance with care and transparency.
