Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the hand with quiet elegance. This semi-set solitaire invites you to choose a center stone that will become the heart of your story.

Crafted in warm 18K rose gold, the slender band curves gently, offering a subtle blush that complements the marquise’s vintage-inspired shape. The low-profile setting ensures the ring sits comfortably for everyday wear, while the hand-polished finish reflects the Brooklyn studio’s meticulous attention to detail.

Each lab-grown diamond option brings clarity and brilliance without compromise, reflecting a commitment to ethical jewelry that honors both beauty and sustainability.

Designed for those who appreciate refined romance, this ring’s slender band and pointed marquise shape elongate the finger gracefully. Its modest height and smooth edges make it ideal for stacking or wearing alongside a wedding band, blending seamlessly with a variety of personal styles.

Should you need adjustments, resizing is handled expertly in-studio to ensure a perfect fit without disrupting the ring’s delicate balance.
