Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it reveals a striking balance of drama and refinement—an invitation to a story shaped by clarity and confident lines. This semi-set engagement ring in 18K white gold offers a sleek foundation designed to showcase an 8 x 4 mm marquise center stone, framed by delicate accent diamonds that enhance its architectural grace.

Crafted with precision in our Williamsburg studio, the band features a low-profile setting that rests comfortably against the finger, ideal for daily wear without sacrificing presence. The cool sheen of 18K white gold complements the diamond’s icy brilliance, while the mounting’s clean angles reflect a modern-minimal aesthetic, emphasizing structure over ornament.

Each lab-grown diamond is selected for its exceptional clarity and ethical origin, aligning with a commitment to sustainability without compromise. The ring’s slender silhouette suits hands that appreciate subtle elegance and works beautifully alongside stackable bands or a wedding band with similar linear accents.

Resizing is available to ensure a perfect fit, with careful finishing to maintain the ring’s smooth comfort fit. Lead times for custom settings are communicated clearly, allowing for a thoughtful design process without rush.
