Lab-Grown Diamond Engagement Ring

Imagine the subtle elegance of a marquise diamond poised to elongate the finger with its tapered silhouette—here, a 6 x 3.5 mm center stone awaits your choice. This semi-set engagement ring in 10K white gold offers a refined foundation, designed with delicate accent settings that enhance the stone’s graceful profile without overwhelming it.

Crafted for everyday wear, the low-profile mounting keeps the ring close to the hand, minimizing snagging while maintaining a sleek silhouette. The 10K white gold band is polished to a smooth finish, balancing durability with comfort for daily life. Each piece is meticulously inspected in our Williamsburg studio to ensure precise fit and finish.

Our lab-grown diamonds provide the same optical brilliance as mined stones, with a clearer conscience—reflecting a commitment to sustainable, ethical jewelry practices.

This design suits those who appreciate subtle drama and architectural refinement, especially flattering on slender fingers or when paired with stackable bands. Its modest height and secure setting make it glove-friendly and ideal for an active lifestyle.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure your ring fits perfectly over time.
