Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as a 10 x 5 mm marquise diamond catches the light—its pointed ends drawing the eye with quiet drama. This semi-set solitaire ring features a 10K white gold band crafted for everyday wear, its low-profile setting designed to sit comfortably beneath gloves or alongside other stackable bands.

Each piece is meticulously finished in our Williamsburg studio, where the smooth comfort fit and secure prong setting ensure durability without bulk. The polished white gold surface reflects a soft glow, enhancing the marquise’s signature brilliance without overwhelming it.

Our diamonds are lab-grown, offering a clear, sustainable alternative that aligns with thoughtful craftsmanship and environmental mindfulness.

This solitaire suits those who appreciate architectural elegance paired with practical design—ideal for hands that favor slender, elongated shapes and a ring that moves seamlessly through daily life.

Should you need resizing, our in-house artisans handle adjustments with care, preserving the ring’s integrity and finish.
