Sunlight catches the elongated silhouette of the marquise diamond, casting a delicate dance of light that seems to stretch beyond the finger. This semi-set engagement ring invites you to choose your own center stone—an 8 x 4 mm marquise that balances boldness with refined grace.

Crafted in warm 18K rose gold, the halo setting frames the marquise with a whisper of smaller diamonds, enhancing its tapered drama while maintaining a low-profile silhouette that slips comfortably beneath daily wear. The band’s gentle curve and polished finish reflect meticulous handwork, ensuring a smooth feel against the skin and effortless stacking with other rings.

Each piece is born from a commitment to sustainability, featuring lab-grown diamonds that offer clarity and brilliance without compromise. This ethical choice aligns with a modern lifestyle rooted in mindful luxury.

Designed for those who appreciate subtle romance and architectural elegance, the marquise shape elongates the finger, lending a graceful presence that suits both delicate and more assertive hands. Its halo setting adds a soft glow without overwhelming the stone’s distinctive form.
