Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that seems to dance with every movement. This three-stone semi-set engagement ring in 18K rose gold frames a 9 x 4.5 mm marquise center with delicate side stones, creating a quiet narrative of balance and elegance.

Handcrafted in Williamsburg, the band’s warm rose hue complements the diamond’s sharp points, while the low-profile setting ensures a comfortable fit for daily wear. Each prong is meticulously finished to cradle the stones securely without excess height, allowing the ring to slip easily beneath gloves or stack alongside other bands.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and brilliance—ethically sourced and crafted with a lighter environmental footprint.

Designed for those who appreciate refined geometry and romantic detail, this ring suits slender to medium finger shapes, enhancing the hand’s natural elongation. Its three-stone layout offers subtle symbolism, perfect for marking a shared journey.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a seamless fit without compromising the ring’s integrity.
