Lab-Grown Diamond Engagement Ring

Sunlight catches the slender silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to elongate the finger with quiet grace. This semi-set solitaire invites you to choose a center stone that will become a personal beacon of light.

Crafted in warm 18K rose gold, the band’s gentle curve is polished to a soft glow that complements the diamond’s sharp geometry. The low-profile setting ensures the ring sits comfortably for daily wear, while the secure prongs cradle the stone with precision, reflecting careful hand finishing in our Williamsburg studio.

Each diamond is lab-grown, offering a clarity and brilliance born from sustainable practices that honor both the earth and your values.

The slender band suits those who appreciate subtle elegance and a ring that layers effortlessly with wedding bands or stackable rings. Its refined shape feels balanced on most hand sizes, especially elongating shorter fingers with the marquise’s tapered form.

Should you wish to adjust the fit, resizing is handled expertly in-house to maintain the integrity of the rose gold finish and setting.
