Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a subtle glow that seems to stretch beyond the stone’s edges. This semi-set solitaire ring frames a 7.75 by 5.7 mm oval lab-grown diamond with six slender prongs, crafted in a fixed two-tone blend of 18k white and 18k white and platinum and 18k white and platinum that balances cool brilliance with structural strength.

The band’s low-profile silhouette rests comfortably against the finger, designed for daily wear without catching or bulk. Each metal surface is hand-polished in our Williamsburg studio to a refined matte sheen, while the 18k white and platinum prongs secure the diamond with quiet precision, allowing light to dance freely through the stone’s glassy, elongated facets.

Our commitment to ethical jewelry shines through the use of a lab-grown diamond, offering clarity and sparkle with a smaller environmental footprint. The ring’s streamlined form suits those who appreciate modern minimalism—its slender shank pairs effortlessly with stacking bands or stands alone as a statement of quiet confidence.

Resizing is available to ensure a perfect fit, crafted with the same care as the original design. Lead times reflect our bespoke process, allowing each piece to be finished to exacting standards.
