Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a subtle, tapered glow that seems to stretch the hand with quiet elegance. This 12 x 6 mm marquise lab-grown diamond is set in a sleek 14K white gold band designed for everyday grace and resilience.

Crafted with a low-profile setting, the ring sits close to the finger, minimizing snagging while maximizing comfort. The white gold band is polished to a soft sheen, balancing durability with refined simplicity. Accents flank the center stone, enhancing its slender silhouette without overwhelming the design.

Each diamond is ethically sourced through lab-grown technology, offering clarity and brilliance with a smaller environmental footprint. This ring’s streamlined form suits those who appreciate subtle sophistication and a secure fit that adapts seamlessly to daily wear.

Its slender shape complements longer fingers and pairs well with stackable bands or a wedding band of similar width. The comfort fit ensures the ring feels light and natural, even after hours of wear.

Should you need resizing, our Brooklyn studio handles adjustments with care, typically within a few weeks to maintain the ring’s integrity.
