Lab-Grown Diamond Engagement Ring

Imagine the moment light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set engagement ring foundation in 18K white gold offers a sleek, low-profile band crafted for everyday grace and comfort.

Hand-forged in our Williamsburg studio, the band’s smooth finish and secure prong setting are designed to cradle an 8 x 4 mm marquise stone, emphasizing its distinctive shape without overwhelming the hand. The slender shank balances durability with refined elegance, making it a natural choice for stacking or solo wear.

Each ring begins with a responsibly sourced lab-grown diamond, reflecting a commitment to ethical jewelry that honors both clarity and conscience. The cool white gold complements the diamond’s icy fire, creating a modern yet understated canvas.

Ideal for those who appreciate architectural lines and a ring that feels as effortless as it looks, this mounting suits slender to medium finger sizes and slips easily beneath gloves or sleeves. Resizing is available to ensure a tailored fit without compromising the ring’s clean profile.
