Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam that seems to stretch beyond the hand. This semi-set three-stone engagement ring in 10K yellow gold frames a 12 x 6 mm marquise center with two delicate side stones, each chosen to enhance the graceful taper and vintage-inspired drama of the shape.

Crafted in Williamsburg, the band’s gentle curve and low-profile setting ensure a comfortable fit for daily wear, while the polished finish reflects light with subtle warmth. The semi-set design invites you to select a lab-grown diamond that meets your clarity and color preferences, allowing a personalized touch to this poetic composition.

Each stone is ethically sourced through lab-grown technology, reducing environmental impact without compromising brilliance or fire. The warm yellow gold complements the marquise’s glassy, elongated elegance, making it a natural choice for those who appreciate refined romance and a ring that feels like an extension of the hand.

Its slender profile pairs beautifully with stacking bands or can stand alone as a statement of quiet sophistication. The ring’s design accommodates resizing and is crafted to withstand the rhythms of everyday life, from morning coffee to evening strolls in Brooklyn’s tree-lined streets.
