Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of an 11 x 9 mm oval diamond, casting a gentle glow that seems to stretch beyond the finger. This semi-set solitaire ring frames the stone with six slender prongs, crafted in a fixed two-tone blend of 18k white and 18k white and platinum and 18k white and platinum, offering a subtle contrast that sharpens the modern-minimal silhouette.

The band’s lightweight construction balances presence with comfort, designed to sit low and close to the hand for everyday wear. Each metal surface is hand-finished in our Williamsburg studio, polished to a soft sheen that complements the diamond’s glassy, architectural elegance without distraction.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and sustainability, ensuring brilliance with a clear conscience. The ring’s streamlined profile suits those who favor refined structure and confident understatement, pairing effortlessly with stacking bands or worn solo.

Resizing is available to ensure a precise fit, crafted with care to maintain the integrity of the two-tone setting. Lead times vary slightly depending on customization but are communicated clearly during the design process.
