Lab-Grown Diamond Engagement Ring

Imagine the elongated silhouette of a marquise diamond catching the soft light of a Brooklyn morning, its pointed ends drawing the eye along the finger with quiet drama. This semi-set solitaire ring foundation in 14K white gold offers a sleek, low-profile bezel setting designed to cradle a 10 x 5 mm marquise stone securely while allowing maximum light to animate its facets.

Each band is hand-finished in our Williamsburg studio, polished to a satiny smoothness that feels weightless against the skin. The comfort fit shank curves gently, making it ideal for daily wear and effortless stacking alongside wedding bands or delicate bracelets.

Crafted exclusively with lab-grown diamonds, this piece reflects a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Its slender form suits those who appreciate architectural elegance and a refined, modern aesthetic. The semi-set design invites you to select a center stone that resonates personally, whether you prefer a vivid color or a particular clarity grade.

Should you need resizing, our Brooklyn workshop offers precise adjustments to ensure a perfect fit without disrupting the ring’s balance.
