Lab-Grown Diamond Engagement Ring

Light catches the elongated curve of the marquise shape, casting a slender, graceful silhouette that seems to stretch beyond the hand. This semi-set halo engagement ring foundation in 18K white gold awaits your choice of an 8 x 4 mm marquise diamond, designed to amplify the stone’s distinctive pointed elegance with a delicate frame of smaller gems.

Crafted in Williamsburg, the band’s smooth, low-profile setting ensures daily comfort while the halo setting adds subtle brilliance without overwhelming the finger. Each piece is meticulously finished by hand, polished to a soft sheen that complements the cool white gold’s quiet glow.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and sparkle with a reduced environmental footprint.

The slender shape suits hands that appreciate refined drama and elongation, pairing beautifully with stackable bands or worn solo for understated sophistication. Its low profile and smooth edges make it glove-friendly and ideal for everyday wear.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a perfect fit without compromising the ring’s integrity.
