Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances across your hand. This semi-set engagement ring invites you to select a 9 x 4.5 mm marquise stone, whose tapered points and graceful curves evoke a quiet drama and elongate the finger with subtle elegance.

Crafted from cool 14K white gold, the mounting is shaped with artisan precision in our Williamsburg studio. The solitaire setting balances a low profile with secure prongs, designed for daily wear without catching or discomfort. Each curve is hand-finished to a smooth comfort fit, ensuring the band feels like a natural extension of your skin.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both your values and the environment. This ring’s refined silhouette suits those who appreciate modern geometry paired with understated craftsmanship, ideal for stacking or wearing solo.

Should you need resizing, our in-house jewelers provide careful adjustments to maintain the ring’s integrity. Lead times reflect our commitment to thoughtful, pressure-free custom design in Brooklyn.
