Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set three-stone ring foundation in warm 14K rose gold invites your choice of a 12 x 6 mm center stone, ready to become a personal emblem of commitment.

Handcrafted in our Williamsburg studio, the band’s gentle curve and secure prong setting balance presence with everyday wearability. The rose gold’s subtle blush complements the marquise’s dramatic shape, while the three-stone layout offers room for side stones that add depth without bulk. A low-profile design ensures comfort beneath gloves or alongside stackable bands.

Each lab-grown diamond reflects a commitment to sustainability, offering clarity and brilliance with a lighter environmental footprint. This ring’s foundation is crafted with precision, inspected for smooth edges and balanced weight to suit daily life.

Ideal for those who appreciate architectural elegance paired with artisanal detail, this mounting adapts beautifully to a variety of hand sizes and styles. Its semi-set nature allows you to select a center diamond that resonates personally, whether you favor classic brilliance or a unique cut.

Resizing is straightforward, handled delicately in-studio to maintain the integrity of the setting and metal finish. Typical lead times vary depending on stone selection and customization.
