Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, confident sparkle that draws the eye along the finger’s natural line. This semi-set engagement ring foundation in warm 18K rose gold offers a sleek, modern-minimal frame designed to highlight an 8 x 4 mm marquise center stone of your choosing.

Handcrafted in Williamsburg, the band’s smooth finish and subtle taper provide a comfortable fit that sits low against the hand, ideal for everyday wear. The rose gold’s gentle blush complements the diamond’s sharp geometry, while delicate accent settings add refined structure without distraction.

Each piece reflects a commitment to ethical jewelry, featuring lab-grown diamonds that combine clarity and sustainability with Brooklyn craftsmanship. The semi-set design invites your personal selection of a marquise cut, known for its dramatic, tapered points and elongating effect.

Its streamlined profile suits those who appreciate clean lines and understated elegance, perfect for stacking or wearing solo. The low-profile setting ensures glove-friendly wear and ease of movement.
