Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of the marquise diamond, casting a slender, luminous shadow that dances with every movement. This 9 x 4.5 mm center stone is framed by a delicate halo, enhancing its tapered drama while maintaining a refined silhouette.

Crafted in warm 14K yellow gold, the ring’s low-profile halo setting ensures the diamond sits close to the finger, offering both comfort and resilience for daily wear. The band’s smooth finish and balanced weight create a natural feel, designed to complement an active lifestyle without sacrificing elegance.

Each lab-grown diamond is selected for clarity and brilliance, reflecting Haejin Jewelry’s commitment to sustainable, ethical sourcing without compromise. The halo setting amplifies light performance, making the marquise shape’s signature sparkle even more captivating.

Ideal for those who appreciate architectural grace with a touch of vintage allure, this ring pairs effortlessly with stacking bands or stands confidently alone. Its streamlined form fits comfortably under gloves and is suited to slender or medium finger sizes, enhancing the hand’s natural elongation.

Resizing is available to ensure a precise fit, with careful attention to preserving the setting’s integrity. Typical lead times reflect the bespoke nature of our Brooklyn studio process.
