Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of a 9 x 7 mm emerald cut diamond, casting a glassy, architectural glow that feels both modern and deliberate. This three-stone semi-set engagement ring in 18K rose gold offers a refined framework, where clean lines and structured balance meet subtle warmth.

Crafted with precision in Williamsburg, the band’s low-profile setting ensures the ring sits comfortably for daily wear, while the smooth finish highlights the rose gold’s soft blush. Each prong is meticulously shaped to cradle your chosen center stone securely, inviting a custom selection that reflects your unique story.

Our lab-grown diamonds provide the same optical purity and clarity as mined stones, with a significantly lighter environmental footprint—an ethical choice that quietly honors both craft and conscience.

The ring’s slender shank and balanced three-stone design suit hands that appreciate architectural elegance without excess bulk, making it ideal for stacking or wearing alone with ease. Its comfort fit and modest height also accommodate glove wear and active lifestyles.

Should you need resizing, our in-studio experts ensure a seamless adjustment without compromising the ring’s integrity or finish.
