Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light that stretches across the hand like a whispered promise. This semi-set halo ring in warm 10K yellow gold frames a 12 by 6 mm marquise center, its pointed ends drawing the eye along a graceful arc.

Crafted with precision in Williamsburg, the band’s gentle curve and low-profile halo setting ensure a comfortable fit that slips easily beneath gloves or stacks seamlessly with other bands. The polished yellow gold shank is hand-finished to a soft glow, balancing durability with everyday elegance.

Each lab-grown diamond is chosen for clarity and brilliance, reflecting a commitment to sustainable luxury without compromise. This ring’s silhouette suits those who appreciate a blend of vintage-inspired romance and modern wearability, especially flattering on slender fingers or those seeking a statement piece with subtle drama.

Should you need a custom adjustment, resizing is handled expertly in-studio to maintain the ring’s integrity and comfort. Lead times are tailored to your design journey, ensuring a thoughtful, unhurried process.
