Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a striking, tapered sparkle that draws the eye along the finger’s natural line. This semi-set engagement ring foundation in 10K white gold offers a refined stage for a 9 x 4.5 mm marquise center stone, framed by delicate accent settings that enhance its sculptural elegance.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle taper and smooth polish, ensuring it rests lightly against the skin. The low-profile mounting balances presence with wearability, designed to slip easily beneath gloves or stack alongside complementary bands without catching.

Each piece is finished with meticulous inspection to meet exacting standards, reflecting the artisan workshop’s commitment to precision and durability. Our use of lab-grown diamonds aligns with a sustainable ethos, offering clarity and brilliance without compromise.

Ideal for those who appreciate architectural grace paired with everyday practicality, this semi-set invites you to select a marquise stone that resonates personally. Resizing is available to ensure a perfect fit, crafted to accompany your hand through all moments.
