Lab-Grown Diamond Engagement Ring

Light catches the elongated curve of a marquise diamond, casting a slender shadow that dances with quiet elegance. This semi-set halo ring invites your choice of a 6 x 3 mm center stone, framed delicately by a circle of smaller diamonds that amplify its graceful silhouette.

Crafted in 18K white gold, the band offers a cool, polished surface that complements the halo’s sparkle while maintaining a low-profile setting for everyday wear. The refined finish ensures comfort against the skin, with a subtle taper that feels natural on the finger.

Each lab-grown diamond is selected for clarity and brilliance, reflecting Haejin Jewelry’s commitment to sustainable, ethical craftsmanship without compromise.

Designed for those who appreciate a blend of vintage-inspired romance and modern precision, this ring suits slender to medium finger shapes and layers beautifully with stackable bands or a wedding band of your choice.
