Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow across the hand. This three-stone semi-set ring in 18K rose gold frames a 10 x 5 mm marquise center with two delicate side stones, balancing modern minimalism with architectural clarity.

Crafted in Williamsburg, the band’s warm rose hue complements the diamond’s sharp facets, while the low-profile setting ensures a comfortable fit for daily wear. Each curve is meticulously polished, and the prongs secure the stones with quiet precision, inviting light to dance through every angle.

Our lab-grown diamonds offer the same brilliance and fire as mined stones, with a commitment to sustainability and ethical sourcing that quietly underpins the design.

The slender shape of the marquise naturally elongates the finger, making this ring ideal for those who appreciate refined geometry and a confident, structured aesthetic. Its semi-set nature allows you to select a center stone that resonates personally, while the rose gold band’s subtle warmth pairs effortlessly with other stackable pieces.
