Lab-Grown Diamond Engagement Ring

Imagine the gentle glow of a 6 x 6 mm cushion-cut diamond poised to catch the light with a soft, vintage-inspired shimmer. This solitaire semi-set ring offers a refined foundation in 18K rose gold, designed to cradle your chosen stone with precision and subtlety.

Crafted in Williamsburg, Brooklyn, the band features a low-profile setting that sits close to the finger, ensuring comfort for everyday wear without sacrificing elegance. The smooth finish and balanced weight create a natural feel, while the secure prongs are engineered to protect your diamond while allowing maximum light to pass through.

Each piece reflects our commitment to ethical jewelry, showcasing lab-grown diamonds that combine clarity and sustainability without compromise. The warm rose gold hue complements a variety of skin tones and pairs effortlessly with other bands for stacking.

This design suits those seeking a modern yet understated engagement ring that fits seamlessly into daily life, especially for hands that appreciate a subtle silhouette. The semi-set nature invites you to select a cushion-cut diamond that matches your personal vision.

Resizing is available to ensure the perfect fit, and our Brooklyn studio welcomes you to explore custom options with no pressure and full transparency on lead times.
