Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc—like a whispered promise unfolding. This semi-set halo engagement ring in 18K yellow gold awaits your choice of a 9 x 4.5 mm center stone, designed to amplify the marquise’s signature brilliance with a delicate frame of shimmering accents.

Crafted in Williamsburg, the band’s warm gold hue is hand-polished to a soft glow, while the halo setting balances sparkle with a low-profile silhouette that sits comfortably for daily wear. The secure prong arrangement ensures the stone’s pointed ends are protected without sacrificing light play or elegance.

Each lab-grown diamond option reflects a commitment to responsible sourcing and environmental mindfulness, offering clarity and fire without compromise.

This ring suits those who appreciate refined drama—its slender shape elongates the finger, pairing beautifully with slender bands for stacking or worn solo as a statement of quiet confidence. Its modest height slips easily beneath gloves or sleeves, making it a versatile choice for everyday life.

Should you need adjustments, resizing is available to ensure a perfect fit, crafted with the same care as the original design.
