Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of an oval diamond, casting a gentle glow that seems to stretch beyond the stone itself. This semi-set three-stone mounting in 18K white gold offers a poised framework for a 12 by 10 mm oval center, its modern-minimal lines emphasizing clarity and architectural balance.

Crafted in Williamsburg, the band’s sleek profile and precise prong setting ensure a secure hold while maintaining a low silhouette that slips comfortably beneath daily gloves or stacked rings. The cool sheen of 18K white gold is expertly polished to a satin finish, highlighting the mounting’s clean geometry without distraction.

Each piece reflects our commitment to ethical jewelry through lab-grown diamonds, chosen for their clarity and sustainable origins. The oval shape’s soft elongation flatters a variety of hand sizes, lending a subtle elegance that complements both minimalist and statement styles.

Should you wish to adjust the fit, resizing is available without compromising the mounting’s structural integrity. Lead times are tailored to your design choices, ensuring a thoughtful, pressure-free experience.
