Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow across the hand. This semi-set three-stone engagement ring invites you to choose a center stone that balances architectural drama with delicate grace.

Crafted from warm 14K rose gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for everyday wear. The side stones cradle the center setting with subtle tension, enhancing the marquise’s tapered points while maintaining a low profile that slips easily beneath gloves or sleeves.

Each ring is finished by hand, inspected for precision, and built to harmonize with your lifestyle—whether stacked with a wedding band or worn solo. The lab-grown diamond option offers a brilliant clarity and ethical transparency, reflecting a commitment to sustainable luxury without compromise.

Ideal for those who appreciate a refined silhouette and a ring that feels as natural as it looks striking, this design complements slender fingers and elongates the hand’s line. The semi-set format allows you to select a marquise diamond that fits your vision and budget.
