Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise center, casting a subtle, confident silhouette across the hand. This three-stone semi-set ring features a 9 x 4.5 mm marquise lab-grown diamond, its sharp geometry balanced by the gentle curve of the 14K white gold band.

Crafted with a modern-minimalist ethos, the setting is designed for everyday wear—low profile and secure, with a smooth comfort fit that rests naturally against the skin. Each prong is meticulously finished in our Williamsburg studio, ensuring the diamond’s clarity and structure remain the focal point without distraction.

Our commitment to ethical jewelry shines through the use of a sustainably sourced lab-grown diamond, offering brilliance without compromise.

The slender white gold band complements slender or average-sized fingers, while the three-stone layout adds dimension without bulk, making it ideal for stacking or wearing solo. Its refined silhouette slips easily under gloves or sleeves, perfect for a life in motion.

Should you need resizing, our in-house artisans handle adjustments with care, preserving the ring’s integrity and finish.
