Lab-Grown Diamond Engagement Ring

Sunlight catches the marquise diamond’s elongated silhouette, casting a slender, luminous shadow across the hand. This 8 x 4 mm lab-grown gem is set low in a 14K rose gold band, designed to sit close and comfortable for everyday wear.

Crafted with precision, the setting features delicate accent stones that enhance the diamond’s tapered drama without adding bulk. The band’s smooth finish and subtle profile make it glove-friendly and ideal for stacking alongside other favorites.

Each diamond is ethically sourced from sustainable labs, reflecting a commitment to clarity and conscience without compromise.

Its slender shape suits hands seeking elegance with a modern edge, especially those who appreciate a ring that moves seamlessly from morning light to evening plans.

Should you need resizing, our Brooklyn studio offers expert adjustments with care to maintain the ring’s integrity and comfort fit.
