Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise shape, casting a slender, graceful silhouette that seems to float above the finger. This semi-set engagement ring in 14K white gold offers a refined foundation, ready to showcase a 12 x 6 mm marquise diamond with quiet elegance.

Crafted with a low-profile setting, the band’s smooth finish and subtle taper ensure comfort for daily wear while allowing the stone’s dramatic shape to command attention. Each curve is polished in-studio, inspected meticulously to meet the standards of fine Brooklyn craftsmanship.

The choice of a lab-grown diamond reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity.

Designed for those who appreciate a slender, elongating effect on the hand, this solitaire mounting pairs beautifully with stacking bands or stands strikingly alone. Its comfort fit and modest height make it glove-friendly and practical for everyday life.

Should you wish to customize the center stone or inquire about resizing, our Brooklyn studio offers personalized guidance with attentive care and transparent timelines.
