Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, radiant beam across the hand. This semi-set engagement ring foundation in warm 10K yellow gold invites your choice of a 7 x 3.5 mm marquise center, known for its tapered drama and ability to visually lengthen fingers with elegant precision.

Crafted with a modern-minimal ethos, the band features delicate accent settings that balance clarity and structure without overwhelming the stone. The low-profile mounting ensures daily comfort and glove-friendly wear, while the polished finish reflects the Brooklyn studio’s meticulous handwork and quality inspection.

Each lab-grown diamond option embodies ethical clarity, reducing environmental impact without compromising brilliance or integrity.

Designed for those who appreciate confident simplicity, this ring suits slender to medium finger shapes and pairs effortlessly with stackable bands or wedding rings of varied textures.
