Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a subtle, graceful sparkle that seems to dance along the finger. This semi-set halo engagement ring foundation in 18K white gold frames a 7 x 3.5 mm marquise center stone with delicate precision, designed to amplify its tapered drama without overwhelming the hand.

Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure comfort for everyday wear, while the halo setting promises a gentle glow that enhances the diamond’s natural brilliance. Each curve is meticulously polished, reflecting the quiet expertise of our Brooklyn studio artisans.

Our commitment to ethical jewelry is reflected in the lab-grown diamond clarity, offering a sustainable choice without compromise on radiance or character.

Ideal for those who appreciate refined elegance with a modern edge, this mounting suits slender fingers and pairs beautifully with stackable bands or a simple wedding band. Its subtle height makes it glove-friendly and unobtrusive for daily life.

Should you wish to customize the center stone or inquire about resizing, our studio offers a seamless, pressure-free experience tailored to your vision and lifestyle.
