Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the finger. This semi-set solitaire ring invites you to choose a 5 x 3 mm marquise center stone, emphasizing the shape’s graceful drama and subtle elongation of the hand.

Crafted in warm 10K rose gold, the band’s gentle curve is balanced by a crisp white gold setting, offering a quiet contrast that enhances the diamond’s brilliance. The low-profile mounting ensures everyday comfort, while the smooth finish and precise prong work reflect meticulous Brooklyn studio craftsmanship.

Each diamond is lab-grown, embodying a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or fire. This ring suits those who appreciate refined romance with a modern edge—its slender silhouette pairs effortlessly with stacking bands or stands alone as a statement of quiet confidence.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as the moment it represents. Lead times are tailored to your custom design choices, with attentive guidance throughout.
