Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand’s natural lines. This semi-set solitaire ring in 18K rose gold offers a refined foundation for a 12 x 6 mm center stone, designed with a low-profile setting that balances presence and practicality.

Crafted in Williamsburg, the band’s gentle curve and smooth finish ensure comfort for everyday wear, while the secure prong setting allows the diamond’s brilliance to unfold without distraction. The rose gold’s warm glow complements the marquise’s dramatic shape, creating a harmonious interplay of light and color.

Each piece reflects a commitment to ethical jewelry, featuring a lab-grown diamond that embodies clarity and sustainability without compromise. The ring’s streamlined design suits those who appreciate architectural elegance paired with subtlety, ideal for stacking or wearing solo.

Resizing is straightforward, handled with care in-studio to maintain the band’s integrity and fit. Whether you choose to complete the ring with your selected marquise diamond or explore custom options, the process is collaborative and pressure-free.
