Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances along the finger. This three-stone semi-set engagement ring in 18K yellow gold frames a 9 x 4.5 mm marquise center, its pointed ends drawing the eye with architectural grace and modern clarity.

Crafted with precision in Williamsburg, the ring’s clean lines and structured setting emphasize the stone’s confident geometry. The low-profile mounting ensures daily comfort, while the warm glow of yellow gold complements the diamond’s brilliance without distraction. Each piece is hand-finished and carefully inspected to meet exacting standards.

Our lab-grown diamonds offer a transparent origin and a sustainable alternative, reflecting a commitment to ethical jewelry without compromise.

Designed for those who appreciate minimalist sophistication, this ring sits close to the hand, making it ideal for stacking or wearing solo. Its slender shape flatters longer fingers and balances well with a variety of wedding bands.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a seamless fit.
