Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise shape, casting a slender, dramatic silhouette that gently elongates the finger. This semi-set halo engagement ring foundation in 18K yellow gold offers a refined stage for a 12 x 6 mm marquise diamond, designed to sit low against the hand for everyday grace.

Crafted in Williamsburg, the band’s smooth finish and subtle taper ensure comfort without sacrificing presence. The halo setting’s delicate frame enhances brilliance while maintaining a low profile, ideal for those seeking a balance between statement and wearability. Each piece undergoes meticulous hand inspection to meet exacting standards of polish and fit.

Our commitment to lab-grown diamonds means this ring supports sustainable luxury with clarity and conscience in equal measure. The warm gold tone complements the marquise’s tapered drama, making it a natural fit for slender or average-sized hands and a versatile choice for stacking alongside wedding bands or daily rings.
