Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a 10 x 5 mm marquise diamond, it reveals a striking balance of drama and refinement, perfect for those who appreciate subtle statement. This semi-set engagement ring features an 18K rose gold band, its warm hue complementing the stone’s tapered points, while the low-profile setting ensures the ring sits close to the finger for everyday ease.

Expertly crafted in Williamsburg, Brooklyn, the mounting is designed with comfort and durability in mind—its smooth edges and secure prongs allow for confident wear without catching. The rose gold finish is meticulously polished to a soft glow, enhancing the diamond’s brilliance without overwhelming it.

Each lab-grown diamond is chosen for clarity and ethical sourcing, reflecting a commitment to sustainability without compromise. This ring’s slender band and modest height make it ideal for stacking alongside wedding bands or other fine jewelry, while its shape naturally elongates the hand.

Should you wish to customize the center stone or adjust sizing, our Brooklyn studio offers personalized consultations to ensure a perfect fit and finish. Typical lead times accommodate careful handcrafting and inspection.
