Lab-Grown Diamond Engagement Ring

Imagine the soft glow of a 6 x 6 mm cushion-cut diamond poised to catch the light with every movement—its gently rounded corners and subtle facets offering a quiet, vintage-inspired radiance. This solitaire semi-set ring in 18K rose gold provides a warm foundation, ready to cradle your chosen center stone with precision and grace.

Crafted in Williamsburg, Brooklyn, the band is designed for everyday wear: a low-profile setting that sits close to the finger, minimizing snagging while maintaining elegant presence. The smooth finish and balanced weight ensure comfort throughout your day, whether worn solo or stacked alongside other favorites.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that deliver clarity and brilliance without compromise to the environment.

Ideal for those who appreciate subtle warmth and modern craftsmanship, this setting complements the cushion shape’s soft glow and vintage charm. Its streamlined silhouette fits comfortably under gloves and layers seamlessly with wedding bands or stackable rings.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without disrupting the ring’s refined profile.
