Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a marquise diamond, casting a slender, dramatic shadow that dances across the hand. This 7 x 3.5 mm marquise center stone is embraced by a delicate halo of pavé-set lab-grown diamonds, amplifying its tapered silhouette with a subtle, radiant glow.

Crafted in warm 14K yellow gold, the ring’s artisan finish reveals hand-polished surfaces and precisely set stones that sit low enough for everyday wear without sacrificing brilliance. The halo setting balances sparkle with a refined profile, ensuring comfort beneath gloves or alongside stackable bands.

Each diamond is ethically sourced from a lab-grown origin, reflecting a commitment to sustainability without compromise on clarity or fire. The ring’s design suits those who appreciate architectural elegance paired with a touch of vintage-inspired detail, ideal for slender fingers or anyone drawn to a statement shape that elongates the hand.

Should you need a custom fit, resizing is available through our Brooklyn studio, where every piece is inspected and finished by hand. Typical lead times accommodate careful craftsmanship, ensuring your ring arrives ready to wear.
