Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the length of the finger with subtle drama. This semi-set solitaire ring offers a refined foundation in 18K white gold, designed to cradle a 9 x 4.5 mm marquise center stone with precision and grace.

The band’s low-profile setting ensures the ring sits close to the hand, minimizing snagging while maximizing comfort for everyday wear. Expertly crafted in Williamsburg, the smooth finish and secure prongs reflect meticulous attention to detail, balancing durability with elegant restraint.

Each diamond is lab-grown, embodying a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity. The slender white gold shank complements the marquise’s distinctive shape, elongating the finger and pairing seamlessly with other bands for stacking.

Ideal for those who appreciate architectural lines and a confident yet understated presence, this mounting invites you to select a center stone that speaks to your personal story. Resizing is available to ensure a perfect fit, crafted with the same care as the ring itself.
