Lab-Grown Diamond Engagement Ring

Light catches the marquise’s tapered points, casting a subtle, elongated sparkle that draws the eye along the finger’s natural line. This semi-set engagement ring foundation in 14K white gold offers a sleek, low-profile frame designed to cradle a 6 x 3 mm marquise diamond with precision.

Crafted for everyday wear, the band’s smooth contour and secure setting ensure comfort without sacrificing elegance. The white gold’s polished finish complements the stone’s sharp geometry, while delicate accent details add refined texture without bulk.

Each piece reflects Haejin Jewelry’s commitment to lab-grown diamonds, combining clarity and sustainability in a responsibly sourced design. The ring’s modest height and balanced proportions make it ideal for stacking or pairing with a wedding band, especially for those who prefer a glove-friendly fit.
