Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This solitaire semi-set ring in 18K yellow gold frames a 12 x 6 mm marquise center with a low-profile bezel ready to cradle your chosen stone securely.

Crafted in Williamsburg, the band’s smooth, comfort-fit curve ensures it sits close to the finger without bulk—ideal for daily wear and effortless stacking. The semi-set design invites you to select a lab-grown diamond that balances brilliance with ethical clarity, all polished to a satin finish that resists scratches.

Each piece reflects a commitment to sustainability, with lab-grown diamonds offering a transparent origin and reduced environmental impact. The narrow shank and subtle setting make this ring glove-friendly and unobtrusive, perfect for hands that move through a busy Brooklyn day.

Resizing is straightforward within our studio, ensuring a precise fit that complements your lifestyle. Whether paired with a wedding band or worn alone, this marquise solitaire adapts with quiet confidence.
