Lab-Grown Diamond Engagement Ring

Under soft studio light, the square silhouette catches a quiet gleam—its edges sharp yet inviting, like a whispered promise. This semi-set solitaire invites a fixed two-tone a 3.3 x 3.3 mm square center, poised to reflect light with a modern geometry that balances strength and grace.

Crafted in a fixed two-tone blend of 18k rose and 18k rose and platinum and 18k rose and platinum, the band offers a subtle warmth against the cool shimmer of its contrasting prongs. The low-profile setting ensures the ring sits close to the finger, enhancing everyday wearability without sacrificing presence. Each piece is meticulously finished by hand in Williamsburg, with careful inspection to ensure smooth comfort fit and enduring polish.

Our lab-grown diamonds provide a clarity and brilliance that align with a commitment to ethical jewelry—minimizing environmental impact while maximizing beauty.
