Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, casting a slender, luminous shadow that feels both intimate and bold. This semi-set five-stone engagement ring invites you to choose a 10 x 5 mm marquise center, its pointed silhouette echoing the quiet drama of a Brooklyn skyline at dusk.

Crafted in warm 10K yellow gold, the band is gently tapered to cradle the stones with a low-profile setting that balances presence and everyday ease. Each side stone is carefully positioned to enhance the center’s graceful elongation, while the polished finish ensures a smooth, comfortable fit against the skin.

Our commitment to lab-grown diamonds means this ring carries a clarity and brilliance born from sustainable innovation, reflecting a modern approach to ethical jewelry without compromise.

Designed for those who appreciate subtle statement pieces, this ring suits slender to medium finger shapes and layers beautifully with other bands, thanks to its refined silhouette and modest height. Its comfort fit makes it an ideal choice for daily wear, whether paired with gloves or worn solo.
