Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points tracing a delicate arc that seems to stretch the hand with quiet elegance. This semi-set halo engagement ring foundation in 18K rose gold offers a warm, rosy glow that complements the diamond’s dramatic shape without overwhelming it.

Crafted in Williamsburg, the band is polished to a soft sheen and designed with a low-profile setting to sit comfortably beneath daily wear. The halo setting, ready to embrace a 15 x 7.5 mm marquise center, will amplify the stone’s natural brilliance while maintaining a refined silhouette. Each piece undergoes meticulous hand finishing and inspection to ensure seamless craftsmanship.

Our commitment to lab-grown diamonds means this ring supports ethical sourcing and sustainability, reflecting a modern approach to fine jewelry. The slender rose gold band feels light and smooth, ideal for those who appreciate a balance of statement and subtlety. Its shape and size suit hands that welcome elongation and a touch of vintage-inspired drama.
