Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the hand. This semi-set engagement ring invites you to choose a 6 x 3 mm marquise stone, ready to be embraced by a halo of finely crafted rose gold.

Hand-forged from warm 14K rose gold, the band curves gently with a low-profile halo setting that balances sparkle and comfort. Each prong is meticulously shaped to secure your chosen diamond while allowing light to dance freely across its facets. The smooth finish ensures a comfortable fit for daily wear, while the halo adds a whisper of vintage romance without overwhelming the finger.

Our commitment to lab-grown diamonds means your ring carries a clarity and brilliance born from sustainable innovation, reflecting a modern approach to ethical jewelry.

This design suits those who appreciate subtle drama and refined elegance—its slender silhouette elongates the finger, while the halo setting complements stacking with other bands or a wedding ring. The low profile keeps it glove-friendly and unobtrusive for everyday life.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure your ring fits perfectly without compromising its delicate structure.
