Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances like whispered promises. This semi-set engagement ring invites you to choose a 9 x 4.5 mm marquise center, its tapered points drawing the eye along a graceful arc.

Crafted in warm 18K rose gold, the five-stone setting cradles the center with a gentle embrace, each side stone enhancing the ring’s subtle rhythm. The low-profile mounting ensures a comfortable fit, designed for daily wear without catching or shifting. Finished by hand in our Williamsburg studio, every curve and prong is polished to a soft glow, reflecting Brooklyn’s artisanal spirit.

Our lab-grown diamonds offer clarity and brilliance with a lighter environmental footprint, aligning with a mindful approach to fine jewelry. The slender band suits those who appreciate romantic refinement and pairs effortlessly with stacking bands or wedding rings.

Resizing is available to ensure the ring fits your hand as naturally as a second skin. Lead times vary slightly depending on stone selection, but we guide you through each step with care.
